Hello, when running with more threads, or when suspending running process I receive StaleObjectStaleException. I tried to get rid of them according to docs (chapter 6.5). I set log4j log4j.logger.org.hibernate.event.def.AbstractFlushingEventListener=FATAL With that log4j setting some stack traces disappeared. When suspending running process I still got | 15:06:59,500 ERROR [Services] problem closing service 'persistence' | org.jbpm.JbpmException: couldn't commit JTA transaction | at
