If i start an Asynchronous method with an IntervalDuration assigned, the interval will be timed from the last 'start' of the method not from the the last execution-end. This causes the Tasks to be launched in parallel if the previous task was not finished because it needs longer than the interval is set. In fact i need a sequential execution of tasks in an asynchron fashion (a thread which runs from application-deploy to undeploy) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4088848#...
