[jboss-user] [JBoss Seam] - Odd Errors and OutOfMemory

I have some odd errors showing up in my Seam app. I am hoping that someone here can provide a little guidance. Caused by: java.lang.IllegalStateException: could not acquire lock on @Synchronized component: mailQueue the mailQueue component is session scoped, isn't synchronized by me, nor can I figure out why there would be any lock contention on it. The error occurs when a property on the component is referenced from a page. Caused by: javax.el.ELException: /email.xhtml @12,50 rendered="#{!mailQueue.expired}": Error reading 'expired' on type com.digitalsanctuary.seam.SessionMailQueue_$$_javassist_4 | at com.sun.facelets.el.TagValueExpression.getValue(TagValueExpression.java:76) | at javax.faces.component.UIComponentBase.isRendered(UIComponentBase.java:370) This happens rarely, but does occur more than once. I also get about 100+ of these: 02:13:30,821 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_58] - Abort of action id 4b7ed37a:bc61:471a5fe3:d8b98 invoked while multiple threads active within it. | 02:13:30,821 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.CheckedAction_2] - CheckedAction::check - atomic action 4b7ed37a:bc61:471a5fe3:d8b98 aborting with 1 threads active! Followed up by: 02:21:47,763 ERROR [STDERR] Exception in thread "Timer-0" | 02:22:31,160 ERROR [STDERR] Exception in thread "Thread-4" | 02:22:41,379 ERROR [STDERR] java.lang.OutOfMemoryError: Java heap space | 02:25:13,302 ERROR [SeamPhaseListener] uncaught exception | 02:27:50,873 ERROR [SeamPhaseListener] uncaught exception And then I'm out of memory and everything blows up from there. Any ideas? The application is very simple, and used to run for months without issue. I don't understand why there would be lock contention issues with the mailQueue, and I don't know what the arjuna coordinator is doing or why it's failing. Thanks!
