Hello,

I am looking for pointers on how to get status or find out what is slowing down
tomcat. I have a java application that seem to hang tomcat at times..

I am using the following configuration:

Sun Java SDK 1.4.2.27, Standard Edition
Red Hat Linux ES
jakarta-tomcat-4.1.27
JAVA odbc data connector to oracle.

Tomcat will slow down and run at 100% of the CPU and I have to restart
the tomcat process. This happen randomly.. I looking to upgrade to jakarta 4.1.30
to see if this fixs the problem..

Looking for a consultant or tips for figuring out how to debug this..

Thanks

Tom

Did you try to increase heap memory via -Xmx option.

I had such problems, when the VM was near the top of max. heap size and
the garbage collector tried to free mem like crazy
