All, I spent a while looking around to find a solution to the jboss + WSMQ problem described in the following page
http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg21255323 specifically 'When distributed transactions are used under very high load, an attempt to put a message to a WebSphere MQ queue may occasionally fail with the reason code MQRC_SYNCPOINT_NOT_AVAILABLE' Where JBoss is configured with WSMQ using XA using the wmq.jmsra.rar JCA adaptor. I found that at busy times I would get a MQRC_SYNCPOINT_NOT_AVAILABLE (2072) where the trasaction would roll back and try again, at the point I would post a message to another queue manager. I couldn't find a solution and almost gave up until I found that by putting <track-connection-by-tx>true</track-connection-by-tx> in the connection data source, IE <tx-connection-factory> <jndi-name>WSMQJmsTest</jndi-name> <xa-transaction/> <rar-name>wmq.jmsra.rar</rar-name> <connection-definition>javax.jms.QueueConnectionFactory</connection-definition> <config-property name="hostName" type="java.lang.String">localhost</config-property> <config-property name="queueManager" type="java.lang.String">QM_TEST</config-property> <config-property name="port" type="java.lang.String">1420</config-property> <track-connection-by-tx>true</track-connection-by-tx> <max-pool-size>20</max-pool-size> </tx-connection-factory> I have probably processed about 500,000 messages since without a single syncpoint exception since I just thought I would post it here to aid anyone else who had the same problem.
