[JIRA] (JENKINS-13617) 64-bit java.lang.OutOfMemoryError: PermGen space

johno edited a comment on JENKINS-13617 64-bit java.lang.OutOfMemoryError: PermGen space Heap dump looks okish, top instance count is java.lang.Class, I would recommend adding the switch -XX:+CMSClassUnloadingEnabled . Looking at the thread dump I see it OOMd in the PeriodicBackup thread. Might be worth trying to disable https://wiki.jenkins-ci.org/display/JENKINS/PeriodicBackup+Plugin temporarily to see if that helps. "PeriodicBackup thread" prio=5 tid=3023 RUNNABLE at java.lang.OutOfMemoryError.<init>(OutOfMemoryError.java:25) at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631) ..
