Memory Management issue with MT in heavy missions

[Lifeguard]

MT is working fine and I'm getting more FPS with it.
MT is working fine in small - medium multiplayer missions.
I Noticed the problem when I was playing on [4YA] TRAINING 24/7 PERSIAN GULF PVE V2.0 BETA US
MT: I played for 15 mins or so and DCS Crashed, I tried again after that once I loaded into the cockpit DCS crashed due to fatal_out_of_memory (crash file) and RAM was full.
without MT: I tried to join the same server, with the same graphics, no change and it worked fine, I had less FPS than MT and the RAM was not full. I played for more than an hour no problem.
I know 16GB RAM is not recommended with heavy missions, but I'm using virtual memory to compensate and looks like Memory Management is not working properly in MT.

RAM: 16GB - Virtual Memory: 40960 MB

Hi, 

it looks like there was some speech lua error and then your gpu crashed. 

Try removing all unofficial mods, or third party apps, run a slow repair of DCS and test. 

Do you overclock at all? 

thanks

[Lifeguard]

Hey BIGNEWY,
I Removed all of the mods except (SRS & Tacview), did a slow repair, cleared fxo and metashaders.
I never overclocked the GPU or CPU.
Tried the same server [4YA] TRAINING 24/7 PERSIAN GULF PVE when it's empty, It's working fine.
I will test it again today when there are players on the server.
Thanks.

It's working fine now, Thanks

Unfortunately The problem still there ! .. DCS crashes every time I'm trying to play on servers like 4YA persian gulf and 4YA Aerobatics online and Rotorheads ..
Tried to do slow Repair and remove the mods and didn't work this time.
Tried the non MT version and it's working fine. and it's fine by me, I can play on the non MT version when I'm joining heavy servers.
but I think the MT version needs optimization in Memory management.

In the meantime, try lowering DCS Preload Radius setting (default is 60000).

[Lifeguard]

Mine is 20000.

[BIGNEWY]

please always include the dcs log from the session it may have clues. 

thank you

@Lifeguard Sorry, I didn't check your log  before asking. I see in your DxDiag that your pagefile space was nearly null at the moment of your August 2 crash.

Page File: 57252MB used, 44MB available

Please ensure your drives have sufficient free space.

Ans as BIGNEWY asked, please attach the latest zip from your Logs folder. The more crash logs you give, the easier it is for us to try and find the source of the problem.

I have been testing DCS today! I tried 4YA Syria server (20-25 players) 4 times with MT and every time when I'm in the cockpit waiting it to load, DCS crashes.
I tried 4YA persian gulf (around 6 players) with MT, I was able to play for like half an hour, then it crashes.
when DCS crashes because memory is full, the log files got corrupted most of the time.
I have 32GB virtual memory, and 30GB Free space in the system drive that contains DCS too.
Maybe 30GB free space is not enough !!! , but for me the non MT version is better in memory management.
I will attach the log files but most of them are corrupted, hope it helps.
Thanks anyway for the support ...

From your log:

0x00000000000276bb (edCore): ed::fatal_out_of_memory + 0x3B

Fatal out of memory

[Lifeguard]

I will try to free some space, and maybe I will buy a new RAM.
Thanks.

[Flappie]

Just in case freeing up some space and buying more RAM does not help, please note that another user with the same "fatal our of memory" error message found out his PC PSU  was the culprit.

I removed Syria map and now I have 95GB Free space in the system and DCS drive, didn't help. same crashes, I will attach the latest crash report

Try a lower shadows setting in DCS.

Monitor your PC memory while playing (open the task manager and display the RAM usage before running DCS), then check it when DCS crashes.

It will help us understand if you have a RAM/pagefile issue, or a PSU issue.

Finally I was able to play for more than an hour without a crash, I increased the Virtual Memory from 32768MB to 49152MB, looks like 16GB RAM needs more than 40GB of pagefile.

Great. I'll keep monitoring this thread just in case.
