Syslog events?

[Usulsuspct]

I have been having trouble with Bad CRC errors, and so after I make changes (like adding new IDE cable etc...) I have been periodically checking the /var/log/syslog for the CRC errors....

Luckily I havent seen any in a couple of days, but I am wondering what some of the other stuff that I do see in the log means, such as:

Oct 11 18:01:00 server CROND[2283]: (root) CMD (run-parts /etc/cron.hourly)
Oct 11 18:10:00 server CROND[2285]: (root) CMD ( /sbin/rmmod -as)
Oct 11 18:20:00 server CROND[2288]: (root) CMD ( /sbin/rmmod -as)
Oct 11 18:30:00 server CROND[2323]: (root) CMD ( /sbin/rmmod -as)
Oct 11 18:40:00 server CROND[2326]: (root) CMD ( /sbin/rmmod -as)
Oct 11 18:50:00 server CROND[2328]: (root) CMD ( /sbin/rmmod -as)
Oct 11 19:00:00 server CROND[2331]: (root) CMD ( /sbin/rmmod -as)

These occur hourly, there are also events that occur daily...etc.

What sort of stuff is going on here?

Thanks

It's the cron daemon that's running jobs which are specified in root's crontab (crontab -e to view/modify)...from your info rmmod is executed every 10 minutes and looks for unused modules to remove...man cron man crontab can give you all the details.Hope this helps.

Nothing to worry about.

It's just the scheduler (cron daemon) running a process that will remove any modules that are not being used other than the normal modules that are always loaded upon startup.

Let's say your particular system boots and loads

ide-scsi
parport
vfat

but you start to use a device that loads module xxxx. After a certain amount of time (hence the cron job) the system is checked to see if that device is still being used and if not, the module is unloaded.

Does that sound correct to everyone?

If Craig is around, I'm sure he would be able to provide a more precise answer.

I guess I wasn't quick enough in the response.

Diffie is correct.

That makes perferct sense....sort of a cleanup routine...

I see that there are routines that run weekly and even monthly....
