Frequent game crashes with multiple MP missions
Acknowledged, WishlistPublic


Often, during mission load when load-bar is almost complete, ARMA 3 will crash with reports like this:

Problem signature:
Problem Event Name: BEX
Application Name: arma3.exe
Application Version:
Application Timestamp: 52e855fb
Fault Module Name: StackHash_0a9e
Fault Module Version:
Fault Module Timestamp: 00000000
Exception Offset: 8c8d1c24
Exception Code: c0000005
Exception Data: 00000008
OS Version: 6.1.7601.
Locale ID: 1033
Additional Information 1: 0a9e
Additional Information 2: 0a9e372d3b4ad19135b953a78882e789
Additional Information 3: 0a9e
Additional Information 4: 0a9e372d3b4ad19135b953a78882e789

Problem event name can also be:

Problem Event Name: APPCRASH (seems this is the most common, not BEX)

If, however, I don't crash during load, the game will always crash while playing, but the duration of up-time can vary. For example, my last play session was King of the Hill and it went something like this:

Load fine - crashed after 25 min.
Load fine - crashed after 2 hrs.
Load fine - crashed after 20 min.
Load fine - crashed after 1.5 hrs.
Load fine - crashed after 7 min.
Load fine - crashed after 5 min.
Load fine - crashed after 6 min.

As mentioned, this happens on many different types of MP missions.
I have no mods installed/running.

Here's what I've done to troubleshoot:

.Latest BIOS
.Memtest86 for 4 hrs. All passes fine, zero errors
.Format and reinstall Win 7, all updates
.Reinstall ARMA
.Verify STEAM game cache
.Various AMD video card drivers, including latest
..Net Framework repair tool
.All unnecessary processes/services off
.No antivirus (off)

I should also note that all this started 2 updates ago (1.14?). Before that, crashes were rare.

My Hardware:

.i5 4670K
.Asus Z87-A
.8 GB 2133MHz G.Skill Ram
.AMD 5850 (1GB)
.1 TB mechanical drive

Hello Iceman;

Were you able to glean anything pointing to a problem on my end?
Do you need anything further from me?



your crashdumps are being analyzed by our programmers. It might take a while to find out what the problem is.

Thank you.

Great to hear, Iceman.

As the game continues to crash, I have more dumps if you need them.

Been 10 days since my initial report. Have your programmers been able to come up with anything?

I see the frequency of crash reports similar to mine increasing, not only here, but around the net as well. Surely you must have some insight by now.


The game continues to crash post 1.18 as originally described. Added additional crash dumps.

After downloading this weeks hotfix, I played for about 35 min. and crashed.

I then deleted all .dll files in the ARMA 3 DLL folder, sans the readme. Restarted STEAM, but did not verify files (obviously). I was able to put in about 28 hours of MP play, most of which was on various King of the Hill servers before it crashed again (faulting module was ntdll.dll - haven't seen that one before). Played another 2.5 hrs. without a crash, then, called it a night.

I can live with a crash every 30 hrs. or so but will continue to monitor and make notes if issues come up.

Take from that what you will.

Game continues to crash with 1.20 and the new memory allocators. My work around still works, however.

I also have similar issues. Multiple crashes daily. I can also provide LOG/DUMPs as needed. Right now trying the following:

  1. Uninstalled/Installed Steam/Game
  2. Delete all temp mission files from profile folders
  3. Reinstalled drivers for most hardware

Will report back if anything gets better. Please let me know if you need any details in the mean time.

Also noticed similar hardware:
Asus Z87 PRO
i5 4670k
nvidia GTX 770
Crucial 480M50

My logs look something like:
Exception code: C0000005 ACCESS_VIOLATION at XXXXXXXXXX

After several months of the above work-around used to avoid crashes, the work-around no longer works. Game has begun crashing again after the 1.34 patch/update. Usually, after a couple of hours of play time.

Also noticed I sometimes get an 'out of memory' windows dialogue screen, something I've never seen before with this system. Played about 1,500 hours of ARMA 3 and have never seen this before. Not every crash produces this error, though.

Here's a link to my new crashdumps:

Submitted this ticket in April. How about a little love, Iceman?

I'm having a similar issue, I've been using the dll fix as well which recently has stopped working. The game is now unplayable. How have you been dealing with this issue sg?
