Fatal Errors with Windows Integrated Server

Question

Every once in a while - 3 or 4 times in the last 3 hours I get a fatal error on the server. The last part of the server log looks like this:
08/03/13 14:27:59 WARNING: ExecutorService.inform Unknown event state3 Ignored

I'll be happy to include the error report file if that is helpful

I'm sorry I have not been able to determine what caused the errors. In many cases I didn't actually notice it until I went to try to use the console or worklist and found the server was down. I then looked at the log to find the error. There was at least once when I was just navigating the console and it died, but I don't ermember exactly where. Nothing I hadn't done before. I'll try to pay more attention.
I just restart the server to recover.
