Cron jobs and CGI scripts run as the user that owns them. Was it either of
those? Can you post the relevant lines from top?
I realize that CGI's run as the user but before the past few days I've only
seen one user via top. It's just in the past few days that I've seen
this. It really freaked me at first...I immediately thought "hack in
progress..." But it been a few days and all VISIBLE signs are that
everything is ok.
I'm logged in as root via SSH.
