Could you please use our memory allocator and then attach the new dump files made on our memory allocator? Also try reproducing the issue without mods. Thanks.

do you have any additional info for this issue? Kind of action pattern like CTD occur when you fire from weapon or something.. Because without it, its really hard to help and everything we will do, will do as a blind fix :-(

It occurred at random. It occurred while flying helicopters and planes, while running, while shooting, and pretty much anything else. It has also occurred in unmodded play. Removing the malloc=system launch parameter seems to have fixed it so far. It has been several hours since I did that and I have not had a CTD since.

interesting.. in fact there are more clues leading to the allocator. Please can you test it for longer period whether removing allocator has helped or hasn't?

It appears that using the system memory allocator may have been the cause. I have played for about 10 hours since I removed that from the launch parameters and not had a crash. While I was having the issue... I was getting crashes anywhere from once an hour, to once every 10 minutes. Thanks guys

good to you ;-) btw. for the next time you want to post some log files to us, please remove command param -nologs before.. this little change could be really helpful than empty log :-)

Oh damn, didn't even notice. Fixed that too. Thanks.

No, is not fixed yet. And I have not Maloc activated, but the game crashed allways 1 to 20 minutes, random.

Pershing:
please could you attach your report log(logging must be enabled) and we will take a look, but I guess that these reports are really connected to the allocator

I have one here http://feedback.arma3.com/view.php?id=25405 at my own report (0025405). Now I am playing Pilgrimage (v1.93) and I must save at any minute, in particular when I drive a MRAP with high speed. And one more nuisance is the failure in save/load with a get shot street lamp. Please take a look at http://feedback.arma3.com/view.php?id=23273 too.
Thankyou.
