This was with the master backend, but I also have the problem with the
slave backend.  Actually it is worse in that it won't run more than a
couple hours before disconnecting.

I can compile with debugging, however it rarely aborts like this.
Usually the slave backend just disconnects from the master, however it
is still running and the logs (without any special verbose statements)
don't seem to show anything particularly interesting (to me).  The
master backend usually just stops commflagging with nothing special
that I can see in the logs.  In these cases while running with
debugging do I just CTRL-C when I notice the issue and post the entire
debugging text or is it not useful if it isn't seg faulting or locking

Thanks for the guidance.
