Opinion Wanted: Hardware or Software problem??


I would like an opinion on what might have gone wrong?

Yesterday midnight my server 'hang' for the second time.
The first time (abt a month ago) was similar scenario, my log stops around midnight.
The next morning, I don't even see anything on my screen but to reboot the server.

I would like to know in this kind of circumstances, is it the hardware or software problem? I also noticed I have sound and USB modules loaded which I don't need. I will probably remove them later.

I have no process that was schedule to run after midnight.

Jul 18 00:48:41 myserver -- MARK --
Jul 18 09:04:40 myserver syslogd 1.4.1: restart.

I am using Slackware 9.0, kernel 2.4.21

For those who want to see my hardware specs, I have included my pci devices, cpuinfo, meminfo, modules loaded

Do you have a cron job that starts at midnight?

Or perhaps, do you have a cron job that starts at midnight about once a month?

Yes, I have two monthly cron jobs scehdule to run 1st day of the month start at 12:30am. One for mail statistics, another backup using rsync.

However, when I ran it individually, it has no problem. I have another similar server which have these two cron jobs running without problem too.

I did not remember the first time it happens, but I will see if it will happens again in Aug 17 to be exact.

The problem could be a conflict between the two cron jobs, i.e. each works OK but when they run at the same time something bad happens. You could try running them one after the other instead of simultaneously.
