Not all django-admin operations require the Django application to be
running, but the updatelayers task does.  When I am not sure whether
everything is running properly I use the netstat command to see what servers
are listening for connections.  Here's a (truncated) sample from the demo
server:

root@demo:~# netstat -tlnp

Active Internet connections (only servers)

:80 is the default HTTP port for apache/httpd, 8080 is the default one for
Tomcat.  The other numbers in this output don't really matter for this quick
test.

Ok, it looks like your GeoServer configuration has something odd about it
that we don't check for; I am guessing that you have a raster layer whose
extent is not properly detected since there is a divide-by-zero error in
some code that calculates an appropriate preview size.  Perhaps you could
skim through your GeoServer configuration and try to manually identify the
coverage with the problem?  If you aren't able to do that, let me know and I
can whip up a script based on gsconfig.py to identify the problem layer.
