STUCK thread equals elevated CPU

Agile PLM 9.3.0.1 Weblogic 10.0

Recently installed Agile 9301 in production.  Three times in the week since go-live CPU has elevated up to 100% (twice on one managed host, once on the other), forcing me to kill Agile on that managed host and restart.  We sure did not see anything like this on the development environment.

    * I'd like to know why this is happening.
    * Obviously I'd like to make it stop.
    * If I can't do that I can take steps to make the problem less deadly to the system.


Installed VisualVM to look inside the JVM.  I've got a STUCK thread that seems to be elevating the CPU past 25% (baseline appears to be around 10%).  Now I have more data to confuse myself with.  Here are the snipped bits relating to this thread from the thread dump.

Howdy, Stranger!
