我收到以下 JVM 崩溃错误。我可以知道如何解决这个问题吗？请参考以下 hs_err 日志。

请问是否可以通过更改JVM参数来解决上述错误？以下是当前使用的 JVM 参数。

-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.
