I do have one like that.  It is so frustrating!  I also have that happen to
my Django (not Satchmo) site http://invisiblecastle.com, which gets one heck
of a lot of traffic.  I think it is a DB race condition, but can't prove it.

However, I don't have any which that happens to which are running on the
latest code, and never on Python 2.5+ (come to think of it).  Since moving
Invisible Castle to SliceHost, it hasn't gone down once.

On my new server at SliceHost, I am running all the Django daemons inside of
"Supervisor", which is an absolutely fantastic Python daemon monitor app
(installable via pip or easy_install).  I'm using the "Superlance" plugin
for Supervisor, which gives me an http "ping" command.  If the server
doesn't respond with whatever I tell Superlance it should look for,
Supervisor emails me and restarts the daemon.  Very very nice, the best
solution I've found in years.

I also like that Supervisor tracks uptime, and has both a command line and
an optional web front end for stats and restarting supervised processes.

In fact, I was just working on a blog entry about my new solution.  I'll be
happy to share my supervisor control scripts with you Daniel, just write me
direct.
