[jboss-jira] [JBoss JIRA] Commented: (EJBTHREE-1330) EJB timer service should use a thread pool to avoid OOM

EJB timer service should use a thread pool to avoid OOM ------------------------------------------------------- Key: EJBTHREE-1330 URL: https://issues.jboss.org/browse/EJBTHREE-1330 Project: EJB 3.0 Issue Type: Bug Components: timerservice-mk2 Affects Versions: AS 4.2.2.GA, AS 5.0.0.Beta4 Reporter: Galder Zamarreño Assignee: Galder Zamarreño Priority: Minor The default EJB timer service used by the EJB3 layer is based on org.jboss.ejb3.timerservice.jboss.JBossTimerServiceFactory which delegates to the standard org.jboss.ejb.txtimer.EJBTimerService. For EJB3 beans using the EJB timer service the thread local pool should not be used. Since the current EJB timer service creates a new thread for each timer being created, the thread local pool will create a matching instance of the bean for that thread. Thus the number of active instances in total can effectively grow unchecked and thus an OOM will occur.
