Error description
WebSphere MQ 7.0.1.10 client using dotnet(WCF) A time out error occurs, uncommitted messages build up on the queue and multiple svrconn connections are created. In the system log you see the following error 2013-11-27 12:13:08.257 - 48545450000000002f020000000000001700000000000000 - WCFCH0313E: The timeout '00:01:00' was exceeeded while attempting to open the channel for endpoint 'jms:/queue?destination=DEST&connectionFactory=connectQueueManag er(*.SVRCONN)&initialContextFactory=com.ibm.mq.jms.Nojndi&replyD estination=MY.CONSUMER' The operation did not complete in the time allowed. The endpoint might be down, unavailable, or unreachable; review the system status and configuration and increase the timeout if required.
