OOM errors at EGBB

[James Carr]

I have a high end system but I do push it to the max, it runs on eyeinfinty across 3 22iinch monitors, however its stable and get good FPS. Accepting that the PMDG NGX is a memory hog also, but after some considerable testing I have found that flights into EGBB will always eventually result in an OOM error.

I can fly around the world, including into other UK2000 scenery areas and suffer no OOM error, leave the sim on overnight at a particular place and fly again next day and still get no OOM error. Yet a quick flight from say EGPH into EGBB will result in OOM error, or even if I can make it to the gate the FSPUIC low memory error will be chiming and eventually leaving the aircraft parked there will crash the sim with an OOM error.

So it seems that there is something specific to EGBB that is slowly causing the memory usage to creep up.

I read on another forum posted by Oliver regarding AES about some issues with FSX and landclass files slowly causing OOM errors due to file placement, with some solutions for copying some of the files into other folders, one user posted that their was a problem with UK2000 Belfast that can cause this, however FILEMON is no longer in use and I find PROCMON screws my system up if I try and use that to try and find the offening files that may be related to UK2000 EGBB.

Anyone got any ideas on this?

I have seen the thread in the AES forum due to a leak causing OOM errors in other airport(s), namely Istanbul & Dublin.

I am on FS9, have left aircraft at EGBB v2 apron for hours and did not experience memory leak.

Mind you I did not install static aircraft or active fleet because I always fly on line (VATSIM) and have AES installed.

I can also add, that when I make and develop airport scenery I use 2 PCs, one for the design and art programs and the other running FS all day long just sitting there. The FS PC is an old Windows Xp with 2GB ram, so if there was a problem with the airport code then my PC would crash as it has hours  to do so.

I only run my airports, so I dont have other addons.

Hello James,

I can tell you that I used to get CTDs somewhat frequently at EGBB in FS9, especially whilst looking to the east/southeast either at a distance or on the taxiway. This occurred with both the UK2000 Part 5 version, and also a freeware version of the airport. If I could tell you with certainty what corrected this problem, I would. I have a suspicion that it was a texture issue with a World of AI aircraft.

Yeah i can confirm this i have 16gb of 2000MHZ corsair i can fly anywhere in the world with or without UK2000 scenery but there is a serious issue with birmingham Flwon from Turkey to EGBB twice and had the same problem both times flown from Turkey to EMA and no issues what so ever its always on finals... thanks Steve

I have watched this thread for a while, and as I never use FS9 I cannnot comment directly. However, it seems that there are two different errors being talked about here, OOMs and CTDs. I have the PMDG 737 NG in FSX and if I fly to Vancouver from LAX I get an OOM about 20 minutes out from Vancouver. But I can do a flight of the same length somewhere else without a problem, so it is probably a combination of scenery complexity and graphic settings which is my problem here, and probably that of James

However, CTDs are something different, and will be caused by totally different factors. From what people have posted above it seems to me that you are talking about approaching EGBB from the north only. If this is so then it cannot be a problem with EGBB that is causing the CTD. It is much more likely that the trouble is caused by an AFD error at a distant airfield.

Perhaps a couple of you can fly into EGBB and note the exact positon and track that you are following when you get the CTD. That way it may be possible to find the cause.

Its FSX i'm using and it is alway on the RWY 33 approach ...

[Norman Dean]

If it is always on the approach to 33 and never to 15 then it is unlikely that the problem is EGBB. There are a number of things that could be the cause, such as ground models of various structures, but one to consider is an error in an AFD file of another airfield. If this is the cause then it will be an airfield that is about 40 deg either side of your heading when the ctd occurs, say from 290 to 010, and between 80 and 160 miles ahead of you. You could take a look to see if you have an addon airfield that fits that criteria, but if you cannot find one then remove all airfields ahead of you that are within this area and see if that cures it.

You can then find the culprit by elimination.

Sorry not responded earlier to this, couldnt get back into the forum

However I have done some more work on this.

Firstly just to clarify, what i was finding strange was that I could fly anywhere in the world, and I mean anywhere, ive done multiple round the world trips, left the sim on over night with the plane parked up, and then flown again the next day to next destination and its virtually always to add on scenery rather than default and each time i have no issues with getting an OOM error(I have the latest FSPUIC which gives you the bong when it getting low)

I could do a flight from say egbb to egph(both UK2000 and photgraphic vfr scenery) and then fly back into EGBB and I would get oom warning on final into brum, regardless of runway) and often by time I would land and be vacating it would completely run out. sometimes if I go into FSPUIC or something like that when the warning is going off and back to the sim, it will help prolong the crash.

In the UK I only have VFR and UK2000 addons I have no other airports from other makers or afcads. I do Have GEX and I do use ASE...and I did have UTX....

Which leads nicely onto the next thing.

I removed UTX europe, and now I can do a flight from EGBB-EGPH-EGBB and no low memory warning or crash!

So seems UTX was a major issue here.

Removing UTX europe as seemed to pretty much fixed the issue.....but

I have still noticed that I can still occasionally after a lot of flying get an OOM error, and again it will be at EGBB rather than anywhere else, i still feel there is something at EGBB or its surrounds that are causing the issues.

What I did notice is that when I was haveing the full issue, was that if I left my view looking down into the cockpit, so not really seeing out of the cockpit at the scenery when at EGBB, then leaving the sim on parked at EGBB would prolong before the error would occurr at EGBB.

Why I highlight it to EGBB, is that although a fairly complex scenery it isnt the most complex UK2000 or in fact other addon scenery, and although I accept Im pushing my sim, with the settings I use surely landing at egll, or flytampa scenery or any of the other addon airports i use should have also given me the oom error?

one note to add i did have the issues with the flashing people at egbb, and have applied the patch from the forum

[Norman Dean]

As I said, James, your's is a different issue to what others are talkng about on this thread. However, the fact that UT being removed has improved the situaltion confirms what I also said about graphic load. You are probably correct when you say that something in the Birmingham area is causing an increase in the use of sytem resource for you, but pinning it down will not be easy. The only way is to take any scenery that could be remotley connected off then adding it back a bit at a time. By the way, I note that you are using the PMDG 737, which of itself creates a big graphic load, so have you tried with other airplanes?

Norman

[Stevie Inwood]

Yeah thanks Norman i will look into it... I mean i have not long took off from EGBB today to Gibraltar no issues what so ever... I will have alook i do know that the only airports i have in the uk are all Gary's including the vol1 -3 VFR Airfields..

[James Carr]

Yes I do use the PMDG 737, which obvioulsy causes the loading, but the point is that taking into account its loading, other complex scenery addons elsewhere in the world, Its only Birmingham that can cause the issues. Other aircraft less likley to happen or as soon. UTX being removed as improved it remarkably however when UTX was still there, flying into EGLL wouldnt cause the issue, only EGBB, now of the two you would expect EGLL to cripple it, especially with the proximity of other UK2000 scenerys.

In the UK I have only garys scenery and Horizons VFR packs, no other scenery, other that AES and GSX.

Taking that into account, and based on fact EGBB isnt the most complex scenery i fly into, it strongly appears that something specific to EGBB scenery is causing the memory issues. Ive made it useable again by removing UTX, but think its worth investigating as if there is a specific thing that is causing a higher memory usage than other scenerys it may cause probelms for other users, and of course it just be nice to know what it is!

referring back to Olivers posting over on AES forum, is there a chance the location of files may have something to do with it?

[David Key]

Just to say that I have all the UK2000 scenery + photo scenery and have never had an oom problem.

David

[Gary Summons]

James, can turn off the 3D cars and don't install the animation, then use the sim like for a while. Those 2 elements use a lot of resources

[Stevie Inwood]

Right i have solved the issue it is nothing to do with Garys airports it is simply a dx9 windows FSX thing... I will explain more tomorrow as i have to go out now. But basically some people will get this some won't depends how much stuff you have going on and how high you have FSX sliders up.... It is all to do with the VAS I will post the fix tomorrow as i have tried this tonight into EGBB and not getting the issue anymore.. Steve
