Try setting the mode to DYNAMIC or keep NORMAL but shorten the txReaperTimeout from 120000 to 2000 or so. There's definitely an inconsistency in the docs: "The default checking period is 120000 milliseconds, but can be overridden by setting the com.arjuna.ats.arjuna.coordinator.txReaperTimeout property variable to another valid value, in microseconds." The reference to microseconds should be milliseconds. http://jira.jboss.com/jira/browse/JBTM-236 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4055698#...
