arma 3 crash 0xc0000005 STATUS_ACCESS_VIOLATION
Need More Info, NormalPublic


playing the game for 1-20 minutes before the crash.
the issue is always reproducible.


Operating System
Windows 10 x64
Additional Information

Happens on campaign mode, server mode, downloadable content as well.
seems from the visual studio debugger that "The thread tried to read from or write to a virtual address for which it does not have the appropriate access"
tried all the suggestions:


This error is very generic. It may be caused by many issues, such as a hardware malfunction, a virus in the computer, but also an error in the game itself. Possible solutions:

Try changing the Memory Allocator you are using (default: "tbb4malloc_bi" - try "system" on Windows 7 and later)
Try joining another server, then rejoin the previous one.
Update the graphics card drivers to a newer version.
Rollback the graphics card drivers to an older version.
Check the temperature of your GPUs and CPUs.
Verify the integrity of the game cache using Steam.
Re-install DirectX.
Uninstall the Visual C++ 2013 Redistributable package (both x86 and x64 version), restart your computer and install the package again (do not use the Repair function).
Run a Windows System File Check tool to repair corrupted system files.

also: tried some other course of action from the same crashes posted here. None worked.

Verify your game files via Steam.
If that doesn't help, launch your game with -noCB, in Arma 3 launcher's parameters tab its the one all the way on the bottom.

if it still crashes, please send me the new report after the game crashing with -noCB being set.

hi it is doing the same to me and i have tried all recommended steps but still with same error

the same thing happened with noCB set

Hi Explodygoboom,

try to run with the next parameters:

  1. Platform 32-bit
  2. command line: <your/full/path/to/Arma 3> -profiles=Profiles -malloc=system -hugePages -noLogs -noCB
  3. Extra threads - mark all the 3

after many tries, this configuration was the most stable for me.

can you tell if a crash occurs when shooting AT on vehicles?
