How to solve JVM Crash?

I got following JVM crash error. May I know how to solve this? Please refer to following hs_err log.

May I know if the above error could be solved by just changing the JVM argument? Following is the JVM argument currently using.

-Xms2048m -Xmx2048m -XX:MaxPermSize=768m -XX:+UseParallelGC

You use an old VM and specify a GC algorithm using an option explicitly non stable :

Options that are specified with -XX are not stable and are subject to change without notice.

(from http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html)

This line of your trace shows that the failure is related to the parallel gc :

VM_Operation (0x000000004138c420): parallel gc failed allocation

So if you don't have a really specific reason to use this parameterization, remove it. You should only choose a GC algorithm when you know why. And update your VM, as it's harder to search for the bugs of this old version.
