[Bug 985489] Re: nova-compute stops processing compute.$HOSTNAME occasionally

[Andrew Glen-Young]

@Serge,

As mentioned in #1 the cluster is running Precise + Essex. Unfortunately
I cannot consistently reproduce the problem, however the problem has
been recurring approximately once per month.

As mentioned in #5 I think that perhaps nova-compute is attempting to
query libvirtd and libvirtd is not responding. Since the query doesn't
seem to time out nova-compute "hangs" waiting for a response which will
never come.

I can only query the system after the problem occurs and I only have
current state and log files to try infer the problem.
