Coincidently one of our customers saw a similar issue moving from 5.5.x to
6.0.x.

I can't provide the stack traces but I can provide the analysis. It looks
Tomcat is being stopped under load. In these circumstances, the connection
created in unlockAccept() in the endpoint may get stuck in the TCP backlog
queue. Since the connection in unlockAccept() is created without a timeout,
this causes the shut down to block forever.

Tomcat 7 already has a configurable timeout for unlockAccept. I will look at
porting this to Tomcat 6.
