Thanks Emile,

I'm not sure what HiPE is, and I haven't been running any unusual plugins.
There was an erl_crash.dump file, but it's dated from the early this month,
so it may be from a previous crash.

The server is running Centos 6.3 on XenServer. I think I need to look at
the Linux VM itself and see if there's something which could be causing it
to be unstable.

Thanks for your advice!
