Responding from the digest version of the mailing list.
Thanks. I had looked for something in Webmin that was controlling what I
thought was occuring in the background, but I didn't see anything that I
would recognize as that. For now I have not turned the background status
collection off, but have changed the interval to be every 55 minutes instead
of every 5 minutes. This is a pretty minimally configured box and only has
one function which is to rsync a backup from another server once a day, so I
can't imagine what would be a load on it in this regard. The crashes were
occuring at seemingly random times during the day, not when the rsync was
scheduled. Most often once or twice a day, but I do recall at least one day
when it occurred about 4 or 5 times. I will keep an eye on it for the next
couple of weeks and see if it continues after changing the interval. If so,
then I will consider turning the background status collection off.

It may be just that the command only crashes occasionally or when the system
is under load, so Webmin's frequent runs trigger the crash. It is possible
to turn off this RPM status collection if you like, at Webmin -> Webmin
Configuration -> Background Status Collection.
