We have had this problem again, below is the trace. Will this be taken care of or is the kernel too old to fix this?

You might want to run a memory tester on the box before assuming kernel as the crashes look fairly random. Thanks for your feedback. Memory tester was run but with no problem discovered. Not yet upgraded to newer kernel due to this: https://bugzilla.kernel.org/show_bug.cgi?id=74011 |
