[jboss-user] [JBoss jBPM] - hibernate stalestateexception error and locking mechanism in

Hey, I have two process instances, each one coming from a different process definition. Each process has a timer and a couple of nodes, the last node has a transition back to the timer as a loop. I start these two process instances. After a while, I get a hibernate stalestateexception (server logs) which occurs rarely and randomly. My question is why ? I do not see which data versionning could be the problem. Process instances are for me quite independent... and do not share data from database. What can be the problem ? Is there a locking mechanism in JBPM for synchronizing jobs ? If yes, could you explain me in details how this locking works ? Thanks LF Using jbpm3.2.3 Server : apache tomcat 5.5x View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4220050#...
