FS9 OOM. It is confusing :(

Recommended Posts

Hey guys. I dont get OOM a lot anymore now but that day i got it since a really long time. I am confusedHere is my specsWindow XP Pro 64 bit (formatted to this to read 4GB ram)Intel Core 2 DUO 6600 -- 2.40GHZ (power supply 600W)RAM = 4GBEN8800 GTS 640mbAnyway when i got OOM, the process was around 1100K (that was when approaching LHR by AEROSOFT)anyway i have pretty much the same add-ons as when i had it before on my old com which was not as powerful and strong but it never got OOM. Settigns were always max and this one i tried reducing settings also but still OOM. Dont know what to do. Please advise. Maybe go to VISTA 32 bit or anything..HELP PLEASE :(Thanks so much.

You should be checking your >>virtual size<< with the process explorer, not task manager.OOMs pretty much happen if VS is over 1700mb. And under XP, mine goes over 1600mb easily. That is 32bit or 64bit.Vista is better in memory management, and this memory-upping doesn't happen, thus OOM also not.

do i have to get process explorer or is it in windows already?so are you saying i might be better off getting vista?i mean this 4gb ram..cant belive get oom..in my old com as i said no oom and i only had 2-3 gb ram

Have you modified your fs9.exe to allow it to use the additional memory? You have to make it /LargeAddressAware for the extra memory and XP64 to do anything. -PaulPrimary RigLiquid CooledIntel C2D E8500 468X9.5 @ 4.45Asus Maximus Extreme2 gigs OCZ Reaper DDR3 @1400Dual OC'd XFX 8800GTX @ 2 gigsDual VelociRaptor 10k 3gb/s RAID-0Dual WD Caviar 500 gig Raid-0Single 150Gig SATA2 Swap Drive28 inch LCD 16XAA/16XAFDual 19 inch LCD'sPCPower and Cooling 1k Quad SLISaitek Yoke, Saitek Rudders, Go-Flight Flap,Gear and Trim Controlhttp://home.comcast.net/~psolk/3monitorsa.htmlBackup RigsIntel E6600 @ 3.2Asus P5N32E-SLI Plus3 Gigs Kingston Hyper XXFX 8600 GTAMD 4000 San Diego @ 2.72 Gigs Kingston Corsair XMS CL2XFX 7900 GTX Raid-0psolk.jpg

Swadep:Check out this thread here at AVSIM:<< http://forums.avsim.net/dcboard.php?az=sho...&topic_id=35574 >>It explains all. The name of the thread is a bit optimistic, IMHO because I have been doing this and have started to get the occasional OOM again after installing some complex payware scenery, so who knows? I think even the original poster has gotten OOMs since then, but give it a shot and let us know how it works for you.

You might want to consider downloading, installing and cleaning house with "scanAFD.exe" which removes duplications. After implementation of this tool, I have never has an OOM.Respectfully:RTH

I have that and just haven't had time to run it yet. I will do that tonight: KORD to Cloud 9's KLAX.

>i mean this 4gb ram..cant belive get oom..in my old com as i>said no oom and i only had 2-3 gb ramThe "memory" referred to by the OOM error has absolutely NOTHING to do with how much physical memory you might have...It is referring to contiguous blocks of "Virtual Address Space," which is a different thing altogether.Even folks running Vista64 with 32GB of DDR can encounter the OOM error!

ScanAFD did not solve my problem. My current suspects are: hardware O/C issue, or FSDreamTeams KORD/KJFK/Zurich sceneries. All of my OOMs began shortly after installing the latter and there seem to be quite a few posts about that issue.

I have been plauged on and off with the OOM issue. The 3GB hack did fix it for me but I couldn't use AES and some other programs did not function properly with the hack added.With that I know many people that do not have the OOM error. I also read a post by Oliver Pabst from Aerosoft saying that many scenery's have land class files in with the regular scenery files (a big FS9 no no as it causes a memory leak). LC files must have their own folder with no texture folder in it otherwise you get the memory leak.Read more on Olivers findings here>>>>http://www.forum.aerosoft.com/index.php?showtopic=19147So double check your scenery files and make sure you do not have wayward LC files. I have since been removing/fixing scenery that have wayward LC files and have removed the 3GB patch. Fingers crossed....

Hey, bud. Thanks for that.How would I know a "wayward landclass file" when I see one? Do they have a special file extension or something? Thanks.

Not really. Most LC files are named such but many are not so it would be hard to track down.Scary thing is some well known addon company's are making scenery's with these memory leak errors (like France VFR and even some Aerosoft scenery's).

Though Vista has been hated by many, for its bugs, now that most of them have been sorted out, I concluded, after MANY tests, that Vista has far better memory management than XP does.An example:8 hours flight, XP: VS=1700-1900mb (OOM when landing), Vista=1100-1300mb (no OOM). Same FS9 installation, all drivers, clean system...I also have FS9 modified as Largeaddressaware, and things are working beautifully since Vista has been on.

All of my OOMs began shortly after installing the>latter and there seem to be quite a few posts about that>issue.While there is no doubt in my mind that FSDT's sceneries are causal to your OOMs, they are only indirectly responsible. They have no "leaks" in and of themselves. I have done extensive testing at those airports (I own all three) and while they use a boatload of memory (JFK with its associated AI uses over 700Mb of RAM on my setup) the memory use doesn't increase over time (I've left all three running for many hours just looking for such anomalies, haven't found a single one).The problem in your case is that by the time you reach those airports, something's already sapped all the memory available and when they attempt to load, there's simply no memory left to give them. In tracking down what exactly causes your OOMs, I'd start by eliminating scenery elements one by one, I don't think there is any other way. I did that for a flight with a Level-D 767 that would go from KLAX (C9) over KMDW (FT) to KORD (FSDT). With everything "on" (weather, 100% AI, Ultimate Terrain, Flight Environment, GEPro), I'd get an OOM approaching Midway. With the weather turned off, I'd OOM in the exact same spot and so on. To make a long story short, it was only after I turned off Ultimate Terrain that I would no longer OOM on that route (with everything else turned on). Since I've turned off Ultimate Terrain completely (I had UT USA, Europe and Canada all patched to their latest versions) I've had little problems with OOMs (in fact, ironically, I only had one...while approaching FSDT's KFJK, flying directly over Manhattan). I'm not saying that UT may be your problem (I don't even know if you have it installed), but it appeared to be the direct cause of the majority of my OOMs. It may be something completely different in your case. In either event, it's good to establish a baseline, a route where you always end up with an OOM (like my LAX-ORD) and then work from there.

What you say makes a lot of sense, and I really appreciate you're input. You've given me a lot to think about and investigate, some of which I've considered and yes I have all patched and updated UTs installed and yes I have had problems with it in the past on other, lesser computers, mainly seasonal CTDs a long time ago.In my case I was getting OOMs everywhere on final including some simple default airports, not just on final at those sceneries, and only after installing those sceneries -- never had OOMs before, ever. Ultimate Terrain has caused CTDs before but not OOMs and not in over a year since I fixed them with their good help. I just installed these 3 airports about a week ago so I haven't had time to do much testing. I didn't have these problems with any other scenery - all the FlyTampa, Simmer's Sky Japan, freeware and even Cloud9s KLAX never gave me a problem -- and unless KJFK is being loaded upon approach to to KSEA I don't think congestion is the problem. My baseline right now, and I think the logical place for me to start is the morning before I installed these fine looking airports.You've given me a lot to look think about though. Any other suggestions/thoughts?

Hi,I had this problem - memory use was within limits and FS9 crashes.I reckoned it could be a pagefile problem. So I did the following:Go to Start and Run and then type "chkdsk /f".This will prompt you to run a check of the harddisk at startup. Type Y. Reboot and let it do the chkdsk. On my 1TB hd, it took about 5 minutes.When I ran that, I discovered that I did indeed have a problem with my HD, where it thought space was allocated when it wasn't. This may or may not have been the cause of the prob. I haven't had a CTD since then, but hey, they're pretty elusive.Cheers,Bryn.

Bryn -- would you just be more specific as to exactly what message you got from chkdsk, and what you did to resolve your issue? Thanks! ;)

Hi Chuck,The message was: "CHKDSK discovered free space marked as allocated in the volume bitmap".Chkdsk with the /f switch automatically fixes this.Cheers,Bryn.

Well, it appears my problem arose because I trimmed back my userva= in my 4 gb switch fix just a little too much. I trimmed it back from 2386 to 2322, and all seems ok now. No more OOMs.
