/usr/sbin/find

["Antonio Rodriguez" <arodriguez31@cfl.rr.com>]

Every morning, at abut 7:15 or 7:30 a.m., some processes eat my scarse
resources, some owned by nobody, /usr/sbin/find; most likely updating the
database used by locate, and so forth. This timing is very bad for me, I
would rather have that done during the night. I havelooked for any cron
scheduled works, but I haven't been able to find one. Where should I look
for them?
It seems that I haven't run any crontab till now, I am the only user and
root, so there is no other possibility.
