Cool. Let me know what app-verifier turns up
Just to clarify something. If you enter "site crashnow" does the process actually exit?
After the lockup occurs a critical low level windows lock is somehow held. This prevents new processes, threads, and sockets from being created. However 10 sockets are pre-allocated for accepting new client connections so for a little bit you can actually connect and login (provided it's an IP match for the hostname because the server can't reverse resolve at this point) but you can't transfer any directory listings or files over a data channel. You can probably use stat -l and still get directory listings over the control connection though. This should also be true of your current connection after it locks up...
