Paul--For the 'flight-simulator-tweaking-challenged' out here can you please explain the process that you follow to check for consistency of names and change them. I know what AIRACs are, and what I am trying to do now, is change the names.Do you think the AIPlayr.dll can be related to that?-----------------------------------------Sergey Kireyevhttp://www.precisionmanuals.com/images/forum/pmdg_pf.jpg

Sergey, I am not sure if this is the root of that particular issue but I would lay money on the fact that your flight that ended in a Out of Memory CTD was caused by this. I think it was KJFK to VHHH or vice versa. I would bet a lot of money if we make these changes you will be able to do that flight no problem...First, locate your appropriate Airac files:LVL-D and PMDG share a file I believe, it is located at program filesFS9FMCWPnavdata PSS uses their own files in program filesFS9PSSNavdata Within that directory there are numerous files. Usually you only need to make the changes in one file but it is good to right click on each file, use the open with option and select notepad. Do a search in each file for the airport name in question just to be sure. Open up wpNavAPT.txt and do ctrl-f for find. Type in KJFK and every single place you find John F Kennedy Intl change it to Kennedy Intl For KEWR, change it from Newark Liberty International to just Newark Intl etc... Do ctrl-f a few times because there will be multiple entries...I really hope this helps Sergey...This is what I have been battling while I was trying to help you. Now that I hope I have my issues resolved I can pay some more attention to you..-PaulLiquid CooledAMD 4000 San Diego2 Gigs Kingston Corsair XMS CL2Dual 7800 GTX 24 inch widescreen dual 19 inch LCDRaid-0

I changed the JFK name in the SID/STARS database for PMDG yesterday. I haven't had a chance to do the rest. As soon as I get to it, I will test and report back to you. Come to think of it, updating my SIDS/STARS and AIRAC from navdata and planepath was one of the last things I did before the dreaded errors started after the VHHH-EGLL flight.I really don't think that AIPlayr.dll error is related, since it happened even when I was using the tower from Traffic 2005. But if I fix the inconsistencies here, at least I will have on less variable to tinker with.PS: I wish I had the space to set things up the way you have it. I really could use a yoke, and a monitor for the overhead. BTW, I have the same main monitor as yours (albeit a 20").Best regards,

great find, Paul! thanks for the great tip. I will see whether this fixes it. We should get a list of inconsistently named airports.So far as you both have stated, JFK, EWR, add to that list PSP if you use Shez' scenery, also SJC is named differetly, its called Norman Y Mineta San Jose in my airports file but my afcad has mineta san jose intl. edit: one more, KSAN should be San Diego Intl-Lindbergh

Paul,I'm having trouble believing that this is it. Wouldn't this be affecting everyone using the PMDG and Level D airplanes? (I assume that the base navdata delivered with these airplanes would contain the same airport names as the latest AIRAC. If not, this problem would only affect those who updated their navdata, which would still be a sizeable number.)I also noticed that the AFCAD for KBWI uses the name Baltimore-Washington Intl, which is one two many characters to fit into the AIRAC navdata format. So, there would seemingly not be any way to match the airport name in the nav database file?If this is a solution for some of the CTD's, it sure sounds like a lot of work is involved each time you want to update the nav database.Don S.

>I'm having trouble believing that this is it. So am I. I am not entirely dismissing Paul's findings - I think he may be onto something but he may be deriving wrong conclusions. As a software programmer I have hard time believing that simple difference between two alphanumeric strings could cause such drastic results - it would take a real dumb, dumb programmer to write something like that.Michael J.http://www.precisionmanuals.com/images/forum/pmdg_744F.jpghttp://sales.hifisim.com/pub-download/asv6-banner-beta.jpg

add to that list PSP if you use Shez' sceneryI have Shez's PSP installed and not had a single problem with it. In fact I recently tested the scenery (just by chance... I was using Filemon and Process Explorer while troubleshooting a system problem that turned out to be a RAM timing issue). I tested in and around PSP for two days... what amounted to 5-6 hours total... and saw nothing out of the ordinary going on in either Filemon or Process Explorer. In fact the sim (and PSP) was so clean that I finally concluded that the software side of the box was fine and turned my attention toward rechecking the hardware.Good luck with your continued research,Greg

Hey Don, I can never answer the question shouldn't it affect everyone when it comes to computers. After working in this industry for the past 12 years, there is no answer to that. There are so many other environmental factors that can be contributing that it is very rare that a problem with computers becomes a common problem amongst every system. I also never claimed this was going to be a silver bullet or a cure for everyone. I claimed that I hoped I had found something that was going to help others. I have seen a lot of complaints about flying the add-on heavies into so called default areas and ending up with this same error. It has to be something in the software combinations... I welcome the banter and the feedback but my goal was not to cure world peace, my goal was to present the knowledge that I had accrued over the past year and transfer it to my fellow simmers.Don, it might be a lot of work but if it fixes my issues it is worth every second, no?Michael, as to your claims of never seeing a character string comparison cause such drastic results, I thought you if anyone would have understood with a programming background. I could very well be deriving wrong conclusions, I could very well be wrong altogether but we will only know if others try and confirm. One other person has confirmed that he is now able to fly into a scenery he has never been able to fly into after making this change. Have you ever used VI? I have seen entire server farms crash because a config file had an erroneous space at the end of a line. Yes, an empty character took down one of the largest companies in the worlds security for 48 hours. All over an extra tap of the spacebar when inserting a string comparison... I have seen much less cause much worse!!!Greg,In your tests were you flying into the scenery with one of the add-on heavies? We are not concerned with the scenery itself, we are concerned with how the scenery reacts to NavData...We can debate it all we want but until others with the same issues try the supposed fix and report on their findings I do not have anything substantial other than my own experience...Just trying to help,-PaulLiquid CooledAMD 4000 San Diego2 Gigs Kingston Corsair XMS CL2Dual 7800 GTX 24 inch widescreen dual 19 inch LCDRaid-0

In your tests were you flying into the scenery with one of the add-on heavies?The Flight1 Commander 112A using their new GPS. Just wanted to make sure that Shez's scenery didn't catch any heat in all this (I believe your hypothesis has some merit... however some folks could read the wrong impression into your original post and assume something is wrong with his KPSP. I fully understand you did not make such a claim).Regards,Greg

Thanks for picking up I did not bring up the scenery Greg, I understand your point completely and I do not want to see any product get thrown under the bus. I do not think that was anyone's intention... Does the 112A use the same Navdata as PMDG, LVL-D etc? I am not trying to pick on you at all, just trying to get all of the variables in play.Thanks Greg,-PaulLiquid CooledAMD 4000 San Diego2 Gigs Kingston Corsair XMS CL2Dual 7800 GTX 24 inch widescreen dual 19 inch LCDRaid-0

No problem, Paul.Does the 112A use the same Navdata as PMDG, LVL-D etc?I don't fly any of the heavies, so I'm probably not the best guy to ask. AFAIK the Commander uses the FS9 Nav database (for the FS9 GPS).Greg

Thanks Greg, I will dig around with the 112 and see if I can figure it out.I think the problem that I am talking about is isolated to the few new add-on heavies we have seen recently and their interaction with certain .bgl's and navdata...Thanks for the feedback,-PLiquid CooledAMD 4000 San Diego2 Gigs Kingston Corsair XMS CL2Dual 7800 GTX 24 inch widescreen dual 19 inch LCDRaid-0

Hi Paul,Thanks for the comments. I actually hope you're on to something as I've got so many problems with CTD's that it would be nice to at least get rid of some of them!Have you tried switching the NavData airport name back to what it was for one of your problem airports to confirm that that was the problem?If you fly into KBWI, for which the NavData name cannot be "fixed" because there aren't enough characters in the Nav Database format (unless the format is more flexible than it looks to me), do you have the problem?Thanks,Don

First, I apologize if you already read this in another forum, alot of us frequent many forums some of us only one or two and I am trying to get as much visibility to this post as possible.Everyone, I really hope this is the final fix. This could get long because it has been almost a year long struggle and I tired everything as you can see below but I think I finally found an issue that might affect a lot of others. If you want the quick fix skip right to the end but trust me it is worth the read. I am sorry that I am going to flood the forums with this post but hopefully I can help someone with my findings.I need some help confirming it so hopefully some others can help. In addition to the list of possible CTD's seen below that I have found through extensive testing (almost a year) I think I may have just found the one final killer I was missing. I literally tried everything in the list below which is basically a compilation of every error message post I have seen throughout the forums.I was down to JUST UTUSA and GE in the US for the past 3 months. No other scenery add-ons. Despite this whenever I would come into the New York area in any of the Heavies, LVL-D, PMDG or PSS I would get the dreaded out of memory error followed by a CTD. I monitored the mem usage and it usually happened with at least 800 megs of PHYSICAL memory available so I knew it was bogus and was being generated by the software. I found ALL of the things below to cause CTD's, NOT the planes You get to read all of these before you get to the breakthrough at the end!!! Any one can be your killer...In no particular order...1. Improper Sid/Star2. Add-on scenery including modified Afcad files3 Modified AI with bad testures as well as bad AI Afcad and Duplicate Afcad due to AI trafiic:3A. AI is a killer. If you use an add-on traffic program, open up the AFCAD to an airport like KJFK. Then open up the surrounding files, KEWR, KLGA. In total you will have something like 1000 AI in a 20 mile span. MT for example lists KEWR with something like 15 runways and gives ILS approaches for helicopters. Now you multiply that by 3 airports in the region and your poor simulator is trying to load 45 runways. All of these files get used even if you are not flying into that particular airport. Remove the Afcad entirely or try even removing surrounding Afcads. You can also manually go in and correct the runway usage. KEWR for example should have 4L/22R closed for landings and 4R/22L closed for departure. Personally I disable 11/29 completely as it is very rarely used in real life. In other words, there is a lot of factors that need to be looked at with AI beyond just texture issues. Duplicate AFCADS or AFCADS with conflicting information will also cause a CTD or OOM message4. Other add-ons while you fly4A Third party programs that when used in conjunction with certain add-ons cause an out of memory. They might be fine alone or with other a/c but there are certain programs that just do not play well with some of the more advanced add-ons.5. How much physical RAM do you use and what your swap file is set to:5A Also a corrupt swap file can cause this error in which case Microsoft.com has a fix for removing and recreating the swap6. How much free space is available on the drive with a swap fileIf a drive is low on space and can not grow the swap it will produce this message7. In the unlikely event it is a hardware memory error: run memtest8. Modified terrain.cfg9. Improperly removed scenery from a previous install10. Improper Render to Texture setting in FS9.cfg11. Landclass files improperly placed. BIG ONE HERE!!! There are some rumors going around that a LandClass file should NEVER have a texture folder and that ANY LC file with a texture folder will cause a leak. That is not true. If the LC file specifically calls a texture file in the texture folder it is referencing then there is no problem. If the LC file does not call any texture files and there is an empty texture folder it will still search the texture folder but it will not free up the memory it uses to search. It looks some more, memory never gets released and you have an Out of Memory error. This is when the there should be no texture folder. People assume anytime they see a LC file it needs to be moved and that is not necessarily the case.Also, do not assume because it is payware it is correct...12. One thing I have found for certain is that it is very rarely ONE add-on causing a problem. It is usually another add-on that might have been added at a later date that forces the issue to surface. Sometimes an add-on that has worked for years will be exposed for the issue it had all along by another add-on you added later. Never assume it is just the plane you are flying OR the last thing you added. It could go much much deeper...Now despite trying ALL of this and getting down to a fresh install, I still ahd CTD's with an Out of Memory. At my wits end I started looking for new solutions I had not heard anywhere else yet. Mark McG. at LVL-D had always mentioned checking the name of the Airports in every Afcad you were using matched the default. For example, if you were using an Afcad for KEWR and the default Afcad said Newark Intl make sure your add-ons used the same name. I finally when I had no other answers decided to check the name of the Afcad matched the name of the Airac files we all use. Sure enough Bingo, KEWR was listed as Newark Liberty International NOT Newark Intl the airport names did not match. I chaged all of the entries in the Airac and set off on my same 9 hour flight from Rome to Newark I have been trying to complete for over 9 months. Incidentally I can always fly into Rome and leave the sim going for days but can never come home. i have been stuck in Italy for months Sure enough I got to my ALTN airport which was KJFK Kennedy Intl in the Afcad and I had the CTD with an Out of Memory error. Here I stopped to cry, take a shot of vodka, cry some more, think about giving up simming forever, throwing the computer out the window and cried some more.Not giving up I went back into the Airac and did a search on KJFK. BINGO AGAIN, this is listed in the AIRAC as John F Kennedy International, not Kennedy Intl. I changed this is every spot in the Airac I found it, there were quite a few entries in different files, loaded up my ASV6 SU3, FsPassengers, FsBuild FlightPlan, Lago Rome scenery, UTUSA, GE 2006, LvL-D 767 the first time, PMDG 744 the second and PSS 77 the final and FINALLY AFTER ALMOST A YEAR I AM HOMEThe sim has been running for hours, no issues at all. I honestly think that the missing link that has been causing so many of us issues since the release of these add-on heavies is Airport name mismatches with Airac files. It is one variable I have not seen mentioned before in any forums and in my case allowed me to complete a flight I have failed at probably 100 times in the past year (ever since the release of LVL-D.)I honestly want to kiss my computer right now. Please others, try this confirm this and give me some feedback. I really hope this is the golden ticket we have all been looking for...Sincerely,-Paul SolkLiquid CooledAMD 4000 San Diego2 Gigs Kingston Corsair XMS CL2Dual 7800 GTX24 inch widescreen dual 19 inch LCDRaid-0http://home.comcast.net/~psolk/3monitorsa.html

Hi Don,I am doing numerous flights in and out of NY with all three heavies and have been for the past few days. Right now I am trying to replicate the issue with the change in place. That is the quickest and easiest way to bust my own theory but so far about 30-40 hours of flight time in and out and not a single crash (knock on wood). Short of that, after a few more flights I already intend to do exactly what you mentioned and revert the code back and see if the problem resurfaces. As for BWI, my only thought is that it only compares the information that is there and nothing else. As long as the characters that actually appear in the Airac Baltimore Washington Int match what is shown in the Afcad, Baltimore Washington Int then the last l is irrelevant. That would just be my quick theory but to be honest it is a bit of a guess (as all of this is...)Thanks Don,-PaulLiquid CooledAMD 4000 San Diego2 Gigs Kingston Corsair XMS CL2Dual 7800 GTX 24 inch widescreen dual 19 inch LCDRaid-0
