Hi Ryan,
also there is a known issue with Windows 2003 and non blocking socket.
Mainly win2003 leaks non paged pool memory and your machine TCP stack
can gets corrupted really fast. I'm currently working with Microsoft
Engineers to help them fixing the problem (reproducing it and issue an
hotfix).
Just add the NP pool column using Task Manager and see it growing forever...
Not often, but this time Java is not guilty!
