I used to constantly get out of memory perm gen space error until about a month back -
Then I read in detail the various garbage collectors for JDK 1.6 *Throughput Collector *Concurrent Low Pause Collector *Incremental Low Pause Collector I decided to use the concurrent collector as described in my settings below. Please make sure that yoy do not mix and match various garbage collector settings. JVM may not behave as expected. -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:NewSize=1G -XX:MaxPermSize=512M -XX:CMSInitiatingOccupancyFraction=80 -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=your path to the dump file -XX:ReservedCodeCacheSize=256m This got rid of all my perm gen space out of memory error. Hope it helps. Thanks, __________________________________ Anurag 301-296-3838 *** Please note my email address has changed.

I don't have much details other than that you can try searching for it. I don't know how much millage it provides either. Also you do know you can increase permGen size. I don't know if that's an option for you or not. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
