@Dagre infact it is very much a Bohemia problem, Go and read the sitrep's and join the dedicated server chat, As per the sitrep from a few weeks ago we have been supplying a number of logs to Bohemia developers (Iceman & Adam) directly via skype outside that group, The latest is they have pinned it down to one of there animations, an animation that only Altis life servers use. Exile and other missions are not using this animation, Unfortunately its taken from 1.54 patch in November until now and us sending a mass number of logs to them as well as another community's to get this far!- http://dev.arma3.com/post/sitrep-00137 "
In order to isolate Altis Life server crashes, our programmers have continued to roll out special profiling executables leading up to Xmas. This has now finally pointed us in the direction of a source problem. Something is going wrong in specific character animations, and we're honing in on a solution.
Also to add the server is not crashing! Arma3server.exe stops responding or runs out of memory (memory leak in killing one of the animations)
