I've started using the -malloc=system command line option and it's made it heaps better. I didn't have any crashes in over an hours worth of gaming, which involved heaps of truck driving and looting some of the bigger towns. I did notice that it started pausing and freezing slightly towards the end of the session but that used to happen to me a few patches back too after longer periods of playing.

I don't even have a swap (paging file) I disabled it a while back because my system was taking forever to shutdown.

My system has 12gb of RAM. I've noticed that DayZ had been using up to about 5gb of memory.

Geez, if you read the additional information field you'll see that I have already tried removing the launch parameters. I removed them before I even started playing the game. I have already attached the DayZ.RPT file to the issue, and have added some rar archives for the other files. it's too large to attach as one file.
