this is not a tomcat, issue, it is your code (or should I say the webservice code) that is locking when trying to read data from the socket.
you should set SO_TIMEOUT on the socket, and it will timeout and throw an error instead of hanging forever when there is no data from the other side.

After removing all System.out.println statements (including printStackTrace()) Tomcat is still experiencing thread locking issues. I just put this on a different machine running Win 2k Server service pack 4. Again, it's been running for over a year on a linux box with no issues. We've also had 2 people developing it on XP and Win2k pro for the year without seeing this. Has anyone else had any problems with threads locking?
