Crash when loading multiplayer
Closed, ResolvedPublic


I have been playing ARMA III successfully since its launch. Starting about 3 weeks ago, I have not been able to enter any MP game. When I choose a MP server, the altis map appears and remains on the screen permanently. I can't alt-tab to desktop. When I ctrl-alt-del to task manager, there is an arma 3 process listed under processes but nothing under applications. There is no arma 3 icon on the toolbar.

I verified cache and reinstalled software via Steam. No improvement. {F23750}


Legacy ID
Game Crash
Steps To Reproduce

Problem occurs on every try, even after reinstallation.

Additional Information

There appear to be other players describing the same behavior in the Arma 3 community forums on Steam.

Thank you for reporting the issue.
We need crash dump files from this folder for solve your problem.
C:\Users\<Name>\AppData\Local\Arma 3\
Can you upload somewhere in winrar package please?
When package will be smaller than 5000k, you can attach it here. When package is bigger, please use some free sharing service and post link here.

How to find correct crashdump file:
Try to make the crash happen
Look into crashdump folder
Upload crashdump with latest date in name (crashdump is rpt + bidmp + mdmp file with same name)

Thank you.

Uploaded .rar file with several .rpt files from several crashes. No other file types (bidmp or mdmp) were in the folder.


it looks like the crash dumps were not created (we need rpt + bidmp + mdmp file). It could be that your game actually did not crash or it crashed and was killed off (via task manager) too quickly for crashdumps to create.

Next time it freezes, please try to wait a minute or two so the dumps have time to create. If there are no crashdumps after then, we'll try to find another solution.

Thank you.

The game does not actually crash until I kill the process in the task manager. The altis map would otherwise stay on the screen indefinitely. I notice that my mouse cursor that is visible on the Altis map is the Window's cursor and changes shape based on the windows that were on the screen when I launched Arma.


few questions to help us focus on the problem.

  1. Are you able to play single-player missions?
  2. Are you joining through Game-Spy or Steam server list?
  3. Are you able to host a multiplayer game (even on LAN)?
  4. Are you experiencing the same behaviour with Steam Dev version?

Thank you a lot for answering these questions. It helps us a big way.

  1. I am able to play SP
  2. Game Spy
  3. Yes, I hosted a LAN game for myself successfully
  4. Not familiar with Steam Dev version

Odd thing happened tonight. I tried a SP game, than hosted the LAN, and then tried to join a server via game spy, and it worked! But I could not repeat this and haven't been able to join anything again.

I have not previously tried connecting via Steam. When I hit connect in the server browser there, it takes me to the Arma 3 main menu, not directly to a game in progress. (Not sure what the expected behavior is)


thank you for the answers. Could you please try to switch to Steam Dev and see if the problem is still present?

You can find how to change to Steam Dev here:

Thank you very much.

I was able to join the one available MP server I found after switching to Development.

Any new ideas on this?

can you please upload new crashdump files of the stable version of the game?
(crashdump is rpt + bidmp + mdmp file with same name)

C:\Users\<Name>\AppData\Local\Arma 3\

Thank you very much!

As I noted earlier, only rpt files exist in that directory.

JeffB added a comment.May 24 2014, 3:51 AM

Is there any new advice on this? The game I purchased is no longer playable.
