Today, after about 20 minutes of logging in my Ubuntu 10.4, I notice the CPU and hard disk usage going up. top revealed that root was running emacs23.

It is basically the same behavior described at Ubuntu Forums

but there is no answer there. Any clue about this?

Was this perhaps after some kind of update? –  Tim Post Aug 3 '10 at 14:20
    
No update today (or the last few days). –  Alejandro Aug 3 '10 at 15:24

Is emacs your default editor? (which means another process my kick it off). What is the parent process? (type "$ ps -ef | grep emacs" and look at the second number, then look at which process has that as the first number). –  Dave Jennings Aug 3 '10 at 20:58
    
emacs is not my default editor. I already kill the process. If it happens again, I will check the parent process. –  Alejandro Aug 3 '10 at 22:32

There is a cron job that executes emacs weekly for updating AUCTeX auto-loads.

You can expect that behaviour if you installed auctex. To confirm, check out if the file /etc/cron.weekly/auctex is pressent.

Exactly! /etc/cron.weekly/auctex is present. –  Alejandro Aug 4 '10 at 13:01
