Increase Permgen: -XX:MaxPermSize=128m -------------------------------------- Key: JBESB-905 URL: http://jira.jboss.com/jira/browse/JBESB-905 Project: JBoss ESB Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Configuration Affects Versions: 4.2 Milestone Release 3 Reporter: Burr Sutter Assigned To: Mark Little Priority: Critical Fix For: 4.2 On windows, modify the run.bat that is created for the ESB Server so that it has a larger than average MaxPermSize set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m -XX:MaxPermSize=128m Otherwise, you'll eventually run out of PermGen space while performing numerous hot deploys/undeploys. It is especially noticeable while working with the BPM capabilites which use a substantial amount of Hibernate which generates classes for data access (persistence of the in-flight process state). -- 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
