Out of Memory Message

[Mark Mylchreest]

I keep getting an out of memory message and then my FS crashes while on approch to EGCC, about 10 miles out. I have loads of free memory and donot have this error message at any other airports. I am running FS9.1. Has anyone else had this problem or ideas on what to do to stop this from happening?

[Gary Summons]

Try turning off all other addons and use a default aircraft, it could be combination effect. No one else to my knowledge has reported this.

[Andrew Entwistle]

My immediate question would be which addon you are flying into EGCC?

It has little to do with the actual amount of memory free, more to do with the standard limits imposed on a 32 bit application that FS9.1 is natively. The application is allowed 2Gb of address space, and FS requires contigous blocks of address space for its operation. Should there be too little contiguous space available, FS quits with the OOM message, even though in real terms you have loads of memory still free...
There are two ways around this, both involve extending the ability of the FS9 executable to address >2Gb... for which you need a utility: http://www.ntcore.com/exsuite.php explorer suite, which allows you to edit the file header. This makes FS9.exe large address aware...
If you do not wish to install a 64 bit OS which does not have the address space restriction of a 32 bit system, then you can look into the 3Gb switch. There are so many links on the Net to how this is done that I will not repeat it here, again...

Informative reply Andrew, thanks for that, I'll make it sticky.

Ive just got a CTD due to no memorey flying into egcc, short flights im fine, but ive jus done a 12 hour from VHHX and i just got about 11 miles away and ba, fs crashed due to no memory, never had this problem before any solution?

[Liam Riley]

Ive only ever ran out of Virtual Memory with an aircraft addon, which was fixed, it was due to the textures used.

I had the old Manchester and it was fine, now i have the extreme my sim crashes after due to no virtual memory when im on approach into egcc,

I did OMDB-EGCC (7 ish hours) fine on the very first release V1.0 or the 1st V1.1 release and landed on one of the 05 runays, CLS A330-200 Emirates

Then i did OJAI-EGCC, (5 hours) yesterdy with the second V1.1 release and and landed on 05R (ILS 111.55), CLS A340-200 Royal Jordanian

Today i did 12hours from VHHX to EGCC and when i lined up to 23R anout 15 miles away my sim crashed. V1.2 (i guess, which fixed the 111.15 to the actual 111.55 ils freq for 05R) CLS A340-300 Cathay Pacific

I love flying into EGCC its my home airport, bu itll be a bummer if i cant cos of the CTD and im not a computer wizz, i cant do the  gig swap unless its dumbed down for me haha because this is what im following

http://forums.simflight.com/viewtopic.php?f=50&t=70063

I run 2% Traffic, and all my settings are on medium apart from a few for this scenery, i have had no other problems with these aircraft anywhere else and with any of your other scenery

Tomorrow im gonna do 2 test flight, both OTBD - EGCC, my first flight will be with 1.2 installed and ill come in on 23R, my second on 05L.

Ill post my results. And at some point next week Matt is coming to help me with the 3 gig swap, and ill re run the tests and post them results.

Im running Windos XP SP3 with FS9.0, 4Gig of ram, a 2.66GHz Duel core processor and your EGCC Xtreme V1.2

And my mate matt has a CTD problem, and hes running Vista 64-bit with 4 gig of ram

[Matthew Mayers]

the details of what my CTD was...

I was flying the PMDG 747 into 23R, no extreme weather..traffic (just flights traffic 2005) was set to roughly 47% i had no other background programs running and id just been on a 6 and half hour flight which i wasnt to pleased to see the dreaded "Flight simulator 9 has crashed" and then it just restarted...

another incident..I was taxing towards the active at glasgow for just a short flight to egcc in a project airbus a320..i was about to taxi onto the runway then it crashed..i thought "oh no not glasgow too" even though glasgow has NEVER had any problems before...so i set up an IFR from glasgow to gatwick and everything was fine..its just..everything egcc related and fs9 seems to fall unconscious 

Ive unistalled egcc extreme, plus any Al addons, reinstalled, updated un-updated afcads..redid the update..everything possible, well to my knowledge..but still nothing

My OS is Vista home premium sp3 64-bit. 4098MB Ram so plenty for fs to sink its teeth into..unless there is a limit on 64bit systems aswell..which there shouldnt be...only on 32bit OS systems. I hope this problem gets resolved soon!!!!! ill be of any help!

[Matthew Mayers]

just to add i have no problems flying out..just in..except for one time where it did crash on me but that was something to do with my anti virus thinking it was hilarious to update whilst i played my game. Ill run some short ifrs into and out of egcc see if i CTD. i had this theory it could be a conflict with different ils frequencies, this latest 1.2 update should fix that i hope so and ill soon find out and report back!!

[Liam Riley]

When i get the CTD its "Your computer is running low on virtual memory" etc, with my experience in memory leaks before, the solution was the textures....Most CLS Aircraft have CTD due to a memory leak, they fixed this by altering th textures, either they were doubled up and just had to be moved into the aircraft folder from the main textures folder, or they were lowered in quality slightly.

could this be the case here? are the textures of the scenery causing this?

im just about to T/O at OTBD for my first flight into EGCC 23R

[Gary Summons]

Seams to be FS9. Maybe we have reached the end of pushing FS9, and you cant add more detail to airports and have have complex aircraft.

I'll post a low res set of textures today, to help FS9 users who get oom.

[Liam Riley]

i hate the sound of low res, i mean, i love the scenery.

i have no problems with gatwick and heathrow extreme, maybe lower the quality to the textures for them?

ill screw the test flights for now then, il do them with the low res set =)

[Gary Summons]

>maybe lower the quality to the textures for them

Same thing Liam, you have to lower the memory usage. The images are allready in smallest format possible. I cant fix the problems of FS9, this OOM thing has been around in FS9 for as long as I can remember, first started with Gatwick, we have for some been pushing FS9 over its edge, and the future lies in a better sim that is capable of displaying more scenery.

A low res set, does not look at bad as it sounds, I have to half the size of the image, I then apply a 'sharpen' to the result, in most places you only notice the difference is you move close to texture. I dont have a magic wand that reduce the load on FS9 but maintain the same resolution and variety of textures.

[Liam Riley]

so if im right, you had this Problem with Gatwick, and you fixed it with reducing the textures?

i hope it works for Manchester, but Matt is coming to help me with the 3gig swap because he is the PC wiz not me haha

[Gary Summons]

>and you fixed it with reducing the textures?

No I did not do that. Im just saying at most all large detailed airports, someone has reported a OOM at some point, its not just the airport your at, but the airports around you at well, if you have a look at the Gatwick forum, you see some FS9 users have problems like a pause, oom or ctd when having Heathrow and Gatwick active and also using a detailed aircraft. We are pushing FS9 too hard, the more the add the more likely it will fall over. The smaller airports like Bristol,Glasgow and Stansted will not suffer as much as they contain less scenery.

This lowres set it only for those who suffer an oom, certainly the majority of users do not get this.

Here's the ZIP below, copy files to the Manchetser\texture folder. I haven't had time to test, so if someting doesn't look right, reinstall the original. You dont have to use the all files, you can pick a choose which ones you replace.

If you install all of them, it should reduce the texture scenery load by 60%, you can also try turning OFF my animation as all animation is quite resource hungry.

ill install them and tell you what they are like

also ill do a test flight and see how it goes

cheers
