Hi, Here is our setup for a request message:

weblogic client 1 ----->QMgr1----->messagebroker--------->QMgr2----->weblogic client 2.

The weblogic client 2 processes the request and sends a response back through the same path, which reaches weblogic client 1 , that does a GET with wait.

Some times ( very rarely though) our messages are timing out. We observed that the request is reaching weblogic client 2 on time and the response is also put back on the reply-to-q on time. But the response msgflow ( messagebroker) is able to GET it after about 4 hours once, and after about 15 minutes later another time. This causes the weblogic client 1 waiting on the response message to timeout. What could be the reasons for this behavior?

Thanks in advance.

ydsk.

My guess would be that one of your channels has ended and is stuck trying to come back up. When the error happens, is it only on a particular message or are all messages delayed?

We saw about 3 such messages so far, in no particular order / pattern. Just random at different times.

Thank you.
