OK, I stopped a bunch of the larger memory using services - mysql and
httpd, and then just ran the webmin upgrade again. Still no indication
in the browser it completed, but when the load in top went down I
assumed all was well.

then I rebooted my server, and now webmin shows: 128 MB total, 80 MB
used while top shows: Mem:    131072k total,    67184k used,    63888k free

Better, but still a big gap. I suppose as my server runs, the memory
usage might creep up to a point, but for now webmin seems able to load
the virtualmin page. But I am not happy about the gap in memory usage
reported,nor the idea that it might take on the order of 30MB of memory
just to load the virtualmin summary page.... that sounds like an awful lot!

Any tips appreciated, as I can't really increase the memory or create
swap space on this server. Can I tune webmin/virtualmin/miniserv to use
less memory? How about mysql? apache is already down to just about nada
- I suppose I could make a thin server and a thick one with php and
perl, but given that I only have maxservers=3 for http, I don't know how
much is to be gained by reducing it to 2...

Best,
