JVM crash with segmentation fault

  • 772

We have a cluster of tomcat servers, just upgraded to debian7/openjdk7/tomcat7 (all from stock debian). Now we had two JVM crash on different machines. Both servers having identical hardware and are configured exactly the same (besides IP Addresses of course)

First Crash:

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007fd0b582123a, pid=6542, tid=140533723084544

# Problematic frame:

We never had any JVM crash before.

I really don't know where to start. Does it look like a hardware fault? JDK Bug? Tomcat Bug?

What is the most probably reason for this?

java

    There were issues with my RAM. We have new RAM in the servers and now everything works. I have tested both OracleJDK and OpenJDK afterwards and I can't see any differences in performance or functionality. The only thing missing in Oracle JDK is full cryptography. So I prefer OpenJDK from now on.
