We've hit this before.  I'm not sure if it was on the same host server 
or not.  Is there any other information we can collect that would be 
useful resolving this?
Or are there any actions we can try to see if we can fix the issue 
(other than a reboot of the host server which seems to do the job, but 
is obviously a bit disruptive to other domUs).
