Hi,

Sorry if i'd hijacked this thread, just wonder is the JMX package bundled together with Tomcat 4.1 as well? or it's only available to Tomcat 5.0 onwards?

Thanx

Can anyone suggest diagnostics to tell what is going on?

Try the usual:
1) enable JMX monitoring (-Dcom.sun.management.jmxremote) and look at
the JVM with JConsole, especially at the heap and PermGen usage

2) get a thread dump (kill -3) and see where everybody is stuck
