[ http://jira.jboss.com/jira/browse/JBAS-1319?page=comments#action_12316821 ] Clebert Suconic commented on JBAS-1319: ---------------------------------------
I uploaded a ServletExample.zip that I was using to test. That file was releasing Classes without any problem. I would assume the problem is something on the jakarta's connection/struts. The application (ServletExample) i uploaded I can even see by -verbose:gc that the classes are being unloaded. I don't know what action we should take, as it's pretty strange an struts application holding a reference into a Tomcat classloader. Maybe this is because of Servlet's properties holded by Struts (during the struts-xml parsing), and a simple application doesn't have that class loaded. If you remember in my analysis, I have two instances of jakarta's collections. I realized later on from my post that these collections are referred by the thread, and this is not done by a static variable in the thread. It's done by a class-variable in the thread. I will try to improve ServletExample.zip in a way to use the same behavior as a Struts-servlet. > 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: Adrian Brock > Attachments: ServletExample.zip, analysis.zip > > Time Spent: 1 week > > 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.
