[rabbitmq-discuss] segfault in beam.smp

Thu Oct 31 16:47:58 GMT 2013

Guys, first of all, thanks for your prompt answers. I will start with Michael suggestion on upgrading Erlang relase.

And on Emile comments, well, will do the tests, initially it seems ok, no alerts/errors at any level. Yes right, no point to mention the three year idea. But anyway, kernel is the same on other stable nodes with HIPE as default, who knows. But still will try to increase the log level of the kernel.

Let you know if I have some other answers,
Thanks

To add to what Michael says, there are a few more things you could do:

Check that you don't have HiPE turned on. HiPE can occasionally lead to problems.

Validate the hardware. Run a memory stress-test. Check whether the error can be repeated on different hardware.

That kernel is pretty recent. The 3 years of stable running could not have been on such a new kernel. Have you ruled out the admittedly unlikely possibility of a kernel issue?
