I have been looking over the posts in the forum and think there is (was) a problem with the same timer executing on each node in a cluster. I have been looking at JobExecutorThread.acquireJobs() and there seems to be some solution in 3.2. However, I am not sure. For one thing there is a line commented out in this method: // jbpmContext.getSession().update(job); Are timers in a cluster a problem and if so is 3.2 going to address it? Thanks much, Mike View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008473#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
