Thanks; that seems to fix the ssh timeout problem.  Now I have another
error that arises consistently every time.  I don't know that the
UpdateError has anything to do with the crash--I'll try to increase the
verbosity and see if I get any more information.  It takes me a few hours
to get to this error each time, so it's hard to troubleshoot.  

Any ideas for fixing this?  Do I need to wipe out my previous increments
and start fresh?
