JBoss frequent crash and problem with JDK version?

Jboss application server is getting crashed frequently in production environment. When Jboss crashed there won't be any shut down messages in the log files. Only Jboss process will killed.We contacted JBoss and they analyzed the log for JBoss and suggested in following mail.


Examining the hs_err_pid2533.log we see the following:

# A fatal error has been detected by the Java Runtime Environment:
#  SIGSEGV (0xb) at pc=0x00002b627c0e063c, pid=2533, tid=47704476666176

From the above we can see that this crash occurred inside the JVM layer, specifically in the GCTaskThread.  Additionally, you are running Oracle's JDK:

  # Java VM: Java HotSpot(TM) 64-Bit Server VM (16.0-b13 mixed mode linux-amd64 )

As this crash occurred inside the JDK layer, and we do not provide this JDK, I would strongly recommend contacting Oracle to determine if there are any known bugs.  Searching their knowledge base I was able to find the following which is very similar:

  JDK-6952590 : SIGSEGV in GCTaskThread

However, I would contact Oracle to confirm that this is issue is a match, or to determine if there is another known issue inside this JDK.

Please let me know if you have any questions on the above.

Anyone from oracle support team , could you please advice on the above issue asap as we are facing this issues frequently.
