Tomcat error: SEVERE: Protocol handler pause failed

Question

I am running apache-tomcat-5.5.23 using java 1.5.0_11 with modjk and Apache 2.0.52 on Redhat Enterprise Linux 4ES. Tomcat does not seem to shutdown cleanly taking a long time to do so displaying the following message in the logs. Any Ideas how to resolve this problem?
I also have
127.0.0.1          localhost localhost.localdomain
in my hosts file amoungst other things.

This problem was resolved by editing the host file (/etc/hosts in the case of my unix box). What had happened in my case was that the box was using the IP address of the external cisco box, when it should have been using its internal IP. So I would recommend looking and checking what your host name resolve to.
Just thought I would add this note as I hate it when people say problem fixed but leave no resolution.
