[ http://jira.jboss.com/jira/browse/JBAS-1319?page=comments#action_12316802 ] Adrian Brock commented on JBAS-1319: ------------------------------------
Correct, this is caused by something holding onto classloaders across deployments. Usually because of static collections in non redeployed classes. Which version did you test? Here is a bug fix for Tomcat 5.0.28 (used in JBoss4.0.1) and ThreadAttributes where just such a static Hashtable was causing a memory leak. The fix was to replace the static Hashtable with a ThreadLocal. http://issues.apache.org/bugzilla/show_bug.cgi?id=33368 http://cvs.apache.org/viewcvs.cgi/jakarta-tomcat-connectors/util/java/org/apache/tomcat/util/log/SystemLogHandler.java?r1=1.5&r2=1.6 JBoss4.0.2RC1+ uses Tomcat5.5 which includes this fix. > redeploy causes OutOfMemoryError > -------------------------------- > > Key: JBAS-1319 > URL: http://jira.jboss.com/jira/browse/JBAS-1319 > Project: JBoss Application Server > Type: Bug > Components: Web (Tomcat) service > Versions: JBossAS-4.0.1 Final > Environment: JBoss 4.0.1 running on fedora core 3, using jdk 1.5.0 > Reporter: Matthew Todd > Assignee: Clebert Suconic > Attachments: analysis.zip > > > Constant redployment, even of a simple web application eventually causes an > OutOfMemoryError in JBoss. > To duplicate, keep on copying a .war package into a servers hot deploy > directory.
