Hey.
I have a lvl 301 COD server and the last few days I have a problem, namely on each map pops up this error: (http://iv.pl/images/28788043603580561026.jpg)
nuke, this pops up is the message count down to the end and changes the map on dd2 then the server crashes.
I do not know what help and please help as soon as possible.
