Message bridge exception when using bridging to MQ

Question

          hi ... was wondering if anyone could suggest what might be causing this.
          I have a weblogic 8.1 queue bridged to a MQ5.3 queue. I was successfully able
          to put messages (using the container to handle the XA) into the weblogic Q and
          have the bridge successfully pass the msg onto the MQ Q. However I have started
          getting the following error msgs on random occasions.(and the bridge is not able
          to transfer the msgs across). Any suggestions as to what might be causing this?
          Please let me know if you need any additional info.
          thanks,
          Rajat

I suggest that you contact BEA Customer Support so that somebody can spend more time working
          directly with you and solving the problem.
          Sorry for not being able to help you more.
