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

[ https://jira.jboss.org/jira/browse/EJBTHREE-1330?page=com.atlassian.jira.... ] Alexander Bollaert commented on EJBTHREE-1330: ---------------------------------------------- AFAIK the workaround specified here just limits the number of corresponding EJB instances. It does not limit the number of timer threads and hence, if you have enough timers (a couple of thousands), it will OOM because it cannot allocate a stack for the newly created native thread. This would mean that the current implementation severely limits scalability (I've been looking in the source code of 5.0.0.GA and it still uses a java.util.Timer per EJB timer scheduling). Maybe it would be best if there is an alternative implementation that uses a ScheduledExecutorService with an adjustable pool size. This would at least prevent the unbounded thread creation problem the Timers exhibit now. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
