Error processing courier, backing off - ESBs stop processing messages --------------------------------------------------------------------- Key: JBESB-1748 URL: http://jira.jboss.com/jira/browse/JBESB-1748 Project: JBoss ESB Issue Type: Bug Security Level: Public(Everyone can see) Components: Rosetta Affects Versions: 4.2.1, 4.3 Environment: Centos(2.6.18-8.el5 #1 SMP, x86_64 GNU/Linux), Sun JDK1.6, JBoss AS 4.2.2, MySQL (5.0.22) Reporter: Ed Bowler Assigned To: Kevin Conner Fix For: 4.4 Hi, I have asked for help on the forums about this here: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=135536 To summarise, after a few days of (reasonably heavy, but happy) usage, the ESB services I have deployed stop picking up messages from their JMS queues, and "Error processing courier, backing off for 32000 milliseconds" is repeatedly written into the log files. I have configured a few datasources to use MySQL instead of the default HSQL (namely esb, jms and juddi). After the suggested upgrade JbossESB to 4.3CR1 I am still getting the "Error processing courier, backing off" error. I now see: {{{ 2008-05-17 10:09:03,558 WARN [com.arjuna.ats.arjuna.logging.arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_58] - Abort of action id a01023a:9f00:482d5dee:eb53a invoked while multiple threads active within it. 2008-05-17 10:09:03,615 WARN [com.arjuna.ats.arjuna.logging.arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.CheckedAction_2] - CheckedAction::check - atomic action a01023a:9f00:482d5dee:eb53a aborting with 1 threads active!
