Hi folks, I tuned by 64 bit JVM using the following parameters. -d64 \ -Xms256m -Xmx512m \ -XX:PermSize=1024m -XX:MaxPermSize=1500m \ -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:-UseGCOverheadLimit \ -XX:+CMSClassUnloadingEnabled \ -server \
After that, I restarted the server about 30 times, and there was no OOM. I was observing the CMS Perm Gen Space using JConsole, and noticed that classes are getting unloaded, and the GC was unloading classes. Can others please try this out and confirm? -- *Afkham Azeez* Senior Software Architect & Senior Manager; WSO2, Inc.; http://wso2.com, * * *Member; Apache Software Foundation; **http://www.apache.org/*<http://www.apache.org/> * email: **[email protected]* <[email protected]>* cell: +94 77 3320919 blog: **http://blog.afkham.org* <http://blog.afkham.org>* twitter: **http://twitter.com/afkham_azeez*<http://twitter.com/afkham_azeez> * linked-in: **http://lk.linkedin.com/in/afkhamazeez* * * *Lean .
