A few messages (50 to 100) per minute. BUT the servlet sends the request via JMS to a backend which sends the answer (normally within 2-5 seconds) back to the servlet. The servlet waits for 4 minutes.
The problem only exists when using two brokers as active-active-cluster - and the listener connects to another broker than the answering backend. Normally there are more than one listener listening on the queue - but since every listener only checks for exactely one message (using the selector) it is important that that message is routed to the correct node. I understood that with the configuration "conduitSubscription=false" the selectors get transfered between the brokers and therefore this system can be used. > It might be worth trying to change the broker url you use to connect the > dynamic client to the broker to something like: > tcp://localhost:61616?wireFormat.maxInactivityDuration=0 > On development (where we see this phenomenon) there is an inactivitity of less than 5 to 10 seconds. On production that may be more (the answers take there up to 2 minutes). Is the timeout of 5 to 10 seconds really a problem?

The problem is, that the listeners are listening and waiting - but on the wrong broker. And the brokers don't shift the message to the right broker. bye, Roland PS: sorry, I forgot to mention the version: we are using ActiveMQ 5.2.0 with the activemq-rar on JBoss-side (connect URL: "failover://(jms1.dev:61616,jms2.dev:61616)?initialReconnectDelay=1000") -- Roland Thomas Lichti IT Telefónica Deutschland GmbH Hülshorstweg 30, D-33415 Verl Tel +49(0)5246-80-1121 Mobil +49(0)160-98949570 Fax +49(0)5246-80-2121 roland.lic...@telefonica.de Telefónica Deutschland GmbH || Georg-Brauchle-Ring 23-25 || 80992 München || www.telefonica.de Telefon: 05246 80-1080 || Fax: 05246 80-2080 || E-Mail: i...@telefonica.de Ust.-Id.-Nr.
