Working memory is not disposed when releasing the RuleSession ------------------------------------------------------------- Key: JBRULES-607 URL: http://jira.jboss.com/jira/browse/JBRULES-607 Project: JBoss Rules Issue Type: Patch Security Level: Public (Everyone can see) Components: JSR94 Affects Versions: 3.0.1 Reporter: Einat Idan Assigned To: Mark Proctor Under heavy load conditions I encountered high cpu and hangs of the system. A thread dump shows all threads being stuck in java.util.WeakHashMap, which is called from AbstractRuleBase.addWorkingMemory (please refer to linked thread). After digging into the code it turned out that the client session object (AbstractRuleSessionImpl) has a release method. This method is supposed to releases all resources used by this rule session. And so it sets the properties, the working memory and the RuleExecutionSet to null: public void release() { this.setProperties( null ); this.setWorkingMemory( null ); this.setRuleExecutionSet( null ); } However, it does NOT dispose the working memory as expected. I added the following line to method: getWorkingMemory().dispose(); Afterwards things improved significantly. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
