OpCode 0x010b
 

More zone crashes:

My zone servers crash after combat. Last thing I see in the zone output regards weapon procs. In world, the last I see (before "client disconnected") is Sending EQWorldPacket OpCode 0x010b (the opcode number at least is correct)

Im running into the exact same problem. I think what is happening is the server is trying to determine your proc chance on your weapon and at the exact same time the mob you are fighting is killed. No idea how to fix it.
