[jboss-jira] [JBoss JIRA] Commented: (JBAS-7710) memory leak in DeadlockDetector

memory leak in DeadlockDetector ------------------------------- Key: JBAS-7710 URL: https://jira.jboss.org/jira/browse/JBAS-7710 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: JBossAS-4.0.5.GA Environment: JBoss 4.0.5.GA with JBOSSTS_4_2_3_SP7 Reporter: Michal Borowiecki Heap dump diagnostics revealed a memory leak in org.jboss.util.deadlock.DeadlockDetector. The more deadlocks are detected the more "waiting" HashMap is growing. In our case the HashMap is >311MB in size. It contains 20 entries, 15 of them are > 20MB in size. The large size is not caused by map values but rather map keys which are of type com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple and contain a large number (couple thousand) of org.jboss.ejb.EntityEnterpriseContext references in its _txLocalResources variable.
