Gordon, thanks a lot. We expect to have no more than 2 connections for each queue, so it's equal to 100 connections. Our queues are static, so such a behavior seems to be a handle leak.

What about connections (qpid-stat -c), how many of those do you expect to have? Are the queues fairly static (i.e. the queues themselves don't really change, just the messages on them)? I guess it is also possible there is some sort of leak of handles(?)... If you could monitor the open file handles during operation (or testing) and observe any patterns that may also help. --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:[email protected] _______________________________________________________ The information contained in this message may be privileged and conf idential and protected from disclosure.
