Dedicated Server crashes after latest update

[yannara 2]

Everything was working fine for a months before latest update arrived. Now we were playing Combat Ops Everon without any mods, and after few hours of playing, the gaming server went down (not the Windows Server OS). Here are last lines during going down. Nothing like this happened before this update.
