I think I have the same error as you.

Is that the error maybe?

having the same issue, in addition to serious FPS issues (below 10)

I've got that memory crash issue too

windows 7 64 Bit
AMD Phenom X4 965
8 GB RAM
AMD Radeon 6870

Same problem. Uploaded screenshot.
i7 4790k
16GB ram
GTX980
Windows 7 64bit

Resource monitor reports system only using ~6GB of 16GB at time of crash

EDIT - I don't have any launch options

Try removing any launch parameters you may have set in steam

I already did. solved the fps problem. memory error still exists

I am having the same issue. No startup options. I have previously used DAYZ fps boost. I have since run the disable function and still no different.

Just got the same memory error crash, Friends have said they get the error when driving the trucks but this results in their death.

The "instruction at '0x7155blablabla' referenced memory at '0x77blablacc0'" error message is what I'm getting

Yep it's annoying as hell. Already reported it when still on experimental.

Eugen Hartons reponse to the memory issues:

In short, add -dologs to launch paramaters and provide them with the logs created by that (users/&user&/appdata/local/dayz).

Hello pilgram15 and thank you for the report.
Please make sure your game is running without any launch parameters as they are not supported and seem to cause various issues within the game. If the issue still persists or you are not using any launch parameters, please run the game with -dologs parameter and attach contents of C:\Users\*USERNAME*\AppData\Local\DayZ to this ticket when the error pops up again.

won't let me attach .mdmp file

I had the same issue, also removing starting parameters and resetting the folders in %HOME/.../DayZ (wiping config) did not help.

However I did notice using the Sysinternals Process Explorer, that directly after starting DayZ, the systems memory "Commit" increases by 7.0 GB to 7.5 GB. That increases my total commit size from around 2.0 GB (after system startup) to more than 9.0 GB.

Whats the "commit" value in Process Explorer? See
http://stackoverflow.com/questions/6598097/process-explorer-what-does-the-commit-history-graph-show

The value has a history graph in yellow, just hover the cursor above the graph.

My system has 8 GB of RAM and I had a swapfile of 1.0 GB in total. After increasing it to a - non-reasonable value - of 8 GB, DayZ does not crash anymore.

I believe it's a bug that DayZ, which is still a 32 Bit application, can somehow gather more than 4 GB of Ram from the system.

To circumvent, just temporarily increase your systems swap file so that you have at least 9 or 10 GB of (virtual) RAM.

(I'll double post @ 0021951)

is swap file the same as the paging file?

yes, sorry, swap file = paging file.

changed my page file to 10 gigs and still crashed.

changed it to 14 gigs, able to last longer now, from ten minutes up to 30 minutes but still crashing.
