    JMSJCA connection pooling issues after upgrading remote MQ from 4.1 to 4.4u

    Christian B
      today we tried to upgrade our system from 4.1 broker conventional
      cluster to the same config in "Version: 4.4 (Build 11-d)"

      after running some hours in production we faced on our application
      servers glaProjectish the following.

      we then rolled the whole package back.

      has anyone any hint where we could start to search for our error? just
      reconfiguring max-pool-size was not the way to go. we did this but it
      just lasted an hour longer and then went crazy with the same symptoms.

      things you should know:
      CAPS version 6u1
      no changes made to the appservers
      we run temor brokers in convetional cluster 5 slaves one master broker no HA
      deployments are CAPS repository based only --> so we do not emss around with connect / disconnect by ourselves


      my question now is is there a way to debug the JMSJCA connection pool somehow?
