login as root, cd /etc and do
ls -l |grep cron
you'll get something like
Code:
-rw-r--r-- 1 root root 321 2007-12-11 18:41 anacrontab
drwxr-xr-x 2 root root 4096 2008-02-13 17:24 cron.d
drwxr-xr-x 2 root root 4096 2008-09-03 18:53 cron.daily
-rw-r--r-- 1 root root 0 2008-02-13 17:24 cron.deny
drwxr-xr-x 2 root root 4096 2007-09-25 18:38 cron.hourly
drwxr-xr-x 2 root root 4096 2008-07-23 21:25 cron.monthly
drwxr-xr-x 2 root root 4096 2008-07-23 21:25 cron.weekly
-rw-r--r-- 1 root root 255 2007-09-25 18:38 crontab
you need to check all those files/dirs. Something is running and you need to know what.
Also, you can predict from that log you've shown when its going to run, so run
top
in an xterm and keep an eye out when you expect it.
