[ http://jira.jboss.com/jira/browse/JBAS-219?page=comments#action_12311141 ] SourceForge User commented on JBAS-219: ---------------------------------------
SourceForge Username: jsimone . Logged In: YES user_id=586242 Thanks for responding Luke, I appreciate it. I am using IBM DB2 Enterprise Edition v. 7.2 with the latest fixpack 7 applied. I am pretty sure you'll see the same thing with the freebee personal edition. Anyway, I'll try and whittle down my application down to just the pertinent code for the failure and attach here. I am really hammering the app server hard with long running tests from multiple clients - or at least trying to - and it hasn't been holding up for me. Any help you can render is much appreciated. I am willing to work with you to make sure this problem is fixed. regards, joe > Out-of-memory Exception > ----------------------- > > Key: JBAS-219 > URL: http://jira.jboss.com/jira/browse/JBAS-219 > Project: JBoss Application Server > Type: Bug > Reporter: SourceForge User > Assignee: Scott M Stark > > > SourceForge Submitter: jsimone . > OS: WinXP Pro > JDK ver: 1.3.1_04-b02 > This occurs in Both 3.0.0 final and 3.0.1RC1.
