Dear Clue less :-)

I had a problem alike once; it was a "find" job, ran by updatedb, by
cron by anacron etc. This was a little noisy, slowing down the system
etc., but it was harmless. What you say sounds harmful.

I dunno what you've got, but this is what I did to solve my "mysterious
process": I had a non-X command line interface open under the "root"
login. Every time the mysterious process started, I switched back to
this CLI immediately and typed in "ps ax >ps1.txt". This dumps the
process list to the textfile ps1.txt

After having collected some textfiles, I compared them. There was one
"find" process that kept coming back. I knew "find" can be responsible
for such noise, so I guessed this was the process I was looking for.
With that info, some newsgroup people could help me on.

So please do this check first. Maybe you'll find that your computer is
defragmentating or whatever... First find the process, then we'll think
about where it came from.
