Subject Re: ActiveMQ stops accepting consumer requests
Date Mon, 30 Jun 2008 09:52:04 GMT

Hi Brian,

can you check the open threads with the jconsole on ActiveMQ during your
run?
I have the assumtion that you will see many Session threads. If the
assumption is true, try the 5.1.0 from ActiveMQ.

Regards
Marco
