Which mod did you play?
Can you reproduce this in Escape from Stratis or Headhunters?

I played last night (3.19.13) for about 1.5hrs on a server running Escape from Stratis and was able to complete the mission. Will try again when i have time.

Played Escape from Stratic and had a crash.....

Just went back into another server and played maybe 5 minutes. Got my loadout at the ammo box, and got in a chopper and crash. Using that virtual ammobox on server.

Can you try reproduce again in Escape from Stratis or Headhunters? New version of game is already on Steam. Thank you.

In Arma 2 if you played for hours you had to flush the RAM or whatever on the card. That doesn't seem to work anymore in Arma 3. Wonder if that would help?

You had to Hold left Shift and hit the minus key on the numpad then type flush. Usually did that every hour or two and had no problems then afterwards.

Do you have still this issue?

Just played 4 hours without issue, will keep testing. Looks like the hold left shift and hit minus key on numpad then type flush is back as well!

Will keep testing.....

Played a few hours today, I think about 3-4 hours and ended with a crash at 5:51pm. Link for dxdiag and game files from profile /App Data/Local/Arma3.

I didn't run the flush command today I wonder if that is why? I did it in the past post just to see if it was added, that might be why I didn't have issues that day. Will play again and after a couple of hours I'll try the flush command.

I see you're running an overclocked CPU. Have you checked what temperature your CPU/GPU are running at? could be related.

Try the latest nvidia drivers, 320.49

Interestingly, your rpt files shows the following as occurring each time just before you crash:

LODShape::AddLoadHandler: Handler not present in shape [a3\weapons_f\acc\reticle_sniper_f.p3d]

Probably unrelated.

Yes I forget what temp I get, I have HAF full tower with lots of fans and V8 cooler on CPU and have run stress tests for 24 hours or so without issue. Running the latest drivers as well.

Will double check the temps....

Just had another crash at 8:33pm. So about 2 hours of game play. Didn't get to run the flush cache, but this was a different, silent crash.

Played for roughly 3 hours no crash, did run the Flush command. Using Real Temp the CPU max was 55C. The GPU Max was 87C. The GPU is a little higher, I dont' recall it going over 85C if I remember correctly. Internet Max says 100C.

CPU 920
GPU SLI 480 GTX's

CPU temp seems fine, the GPU is a little high. You could try blasting it with some compressed air to remove any dust that's trapped in its heatsink.

I cleaned the whole case, little bit of dust nothing caked on or thick. Most likely no difference made. This only happens with Arma, but Arma is probably the only game I can sit down and play for 4+ hours too.....lol

We need repro mission or repro steps for solve your crash. Are you able to create it? Thank you.

Not sure what you really mean? I'm just playing randomly on servers in multiplayer.

This means, that nothing helpful is in crashdumps and without reproduce this crash, we can't do anything with this crash.

Just playing multiplayer is not enough repro for localizing crash.

Oh that makes sense.....being dense here! Didn't know what the heck repro was!

I'm not sure what to say then.....if I mess around in the editor and play around or play local no problems. I have been playing alot of Pay Day 2 beta recently and no problems.

As soon as I go online to play Arma 3 on multiplayer it usually crashes after a few hours. And I only connect to servers with a low ping and a fair number of users of like 25-40 or so. So I connect to random servers all the time, but usually they are favorite servers among people.

Maybe its a hardware problem then, but no other game crashes.

Odd crashing then.....

Hi, do you have these issue in actual version?
Thank you for more info.

Closing this issue.
