After a high cpu load, jms processing comes to a stop.

Solution Unverified - Updated -

Issue

  • Messaging cluster is providing queue(s).
  • Client (clustered) is sending/receiving messages from/to cluster remotely.
  • Client is impacted by "high CPU" for some time, so that the processing comes to a pause.
  • After impact disappears the server doesn't recover fully, what can cause message losses and duplicates?

Environment

  • JBoss Enterprise Application Platform [EAP] 6
    • HornetQ as default JMS provider
