Server pegging 100% cpu then tossing users

Title: Server pegging 100% cpu then tossing users

Version: 0.5.3

OS: Windows 2003 R2 64bit

Java Version: 1.7

Description of Problem:

Every things going great, then people start lurching. It continues until the server ramps the cpu usage to 100% on all 4 cpu's. Java.exe is using all the cpu. It will actually pull all 8GB of ram I allocate to the server exe file within hours.

I have pasted the part of the log when it starts and it dumps all the users, they get back on for about 10 mins and its all over again.

I'm beginning to think its a memory leak somewhere in 0.5.3
