    There seems to be a new crash exploit effecting quite a number of servers

    9gigsofram looks almost like a ddos attack. just by looking at what it says which included playerconnection and packets looks like it has something to do with the servers connection and too many packets being sent at one time which is exceeding the vm limit and causing the crash.

    9gigsofram Can we see some of the console messages before and after that snippet of error?
