Have you monitored the memory usage? And the free memory available on the system? Also, is this running in a VM or a physical machine? The growableArray.cpp is often used to increase the ehap or permgen size. You might try setting -Xmx and -Xms to the same value, ditto for -XX:PermSize and -XX:MaxPermSize. Doing this will set the memory spaces at their maximum and prevent increasing or shrinking of the size, which should help avoid the problem. I find is rather unusual that you are getting an out-of-memory error when you are using only about 2GB of the 6GB of memory that you have available. Finally, you should report this to Sun - the JVM should not crash like this. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4243561#...
