Symptoms

After installing the latest Hotfix the J2EE version of the BPM product started sending multiple UDP messages per  second. The network routers are showing very high CPU usage. After enabling cluster and tribes debug by setting the -Dalbpm.engine.j2ee.cluster.tribes.log.redirect=true and -Dalbpm.engine.j2ee.cluster.debug=true I can see in the log hundreds of Apache Tribes messages per second.

Changes

 Latest BPM 10.3.3 hotfix was applied.
