thanks for the information.
I did notice that on our test servers, it doesn't happen as frequently.
And in the production server.xml we had:
<Sender
className="org.apache.catalina.cluster.tcp.ReplicationTransmitter"
replicationMode="pooled"/>
In the test one it was:
<Sender
className="org.apache.catalina.cluster.tcp.ReplicationTransmitter"
replicationMode="asynchronous"/>
What is the better way?

probably is the multi cast receiver that freaks out. This can happen if the network cable is unplugged. I will add in a sleep on the receiver so that even in this case it wont freak out.
so in the scenario above, its a known problem, checking in a fix right now. if you do provide a dump however, we will know more. or even better, profiling it.

No, not using Apache to front end. Haven't done any thread dumps...yet.
I just was throwing feelers out to see if there is any history of this.

Are you using apache in front of tomcat? Have you done thread dumps when in a good state vs a 100% cpu state? Sounds like an inifinite loop.
