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

WHAZZAMATTAYOU????You don't like spending a year in Italy????Kiss your fanny goodbye - Guido is on his way to see you.Seriously, that's a lot of good work - I've been lucky - I've never had a ctd ( other than a fluke graphic issue ) BUT I use no AFCAD or airac files. I'm sure this will help a lot of people.Vic ( yes, I'm Italian-American :) )Visit the Virtual Pilot's Centerwww.flightadventures.comhttp://sales.hifisim.com/pub-download/asv6-banner-proud.jpghttp://www.jdtllc.com/images/rcv4bannersupporter.jpg
