Greetings folks, I am a first time poster.
I am using Tomcat 4.1.27 on AIX. I have one customer that observes Tomcat
falling into a state of unresponsiveness, cleared only by a restart of the
Tomcat java process. The symptom of the problem is that after several hours
of inactivity, the ability to serve any JSP pages ends, yet the Tomcat java
process is still up and the TCP server port still appears as LISTENING in
netstat. The only evidence I have found of a problem is the following
snippet inside the catalina log. Can anyone explain the
java.net.BindException is within this sequence and what might cause it?
Also, I'm not very skilled (yet anyway) at field troubleshooting Tomcat
(i.e. tracing or debug options). Are there any good guides or articles that
cover troubleshooting? Thanks for any tips.
