Systems Crash Auto Reboot Script
 

I have kind of the same problem, My Redhat system seems to crash on time every time. like 4.20 am every saturday morning. and around 8.20 pm saturday night. I belive this crash is due to a mail cron, that is sending out my members mail and reminders to the users on my site. Yes my logs show no reason for a crash and no errors are loged during crash time. I did just now add the log to my syslog. ( thank you ) hoping it will help me trouble shot my problem, But what i would realy like is some type of script that would reboot my pc when this crash happends. Right now I have to run in town every time just to flick a switch so it will run fine all week. Does any one have a script that can reboot a pc on crash. ? I was thinking wake up on lan but that basicaly only boots the pc from a cold shutdown.. Since ssh no longer works when the pc crashes.. an auto reboot script would be great.

Please help.. Peach :confused:

Just realized that we never did post our findings about the crashes. Turns out it WAS a harddrive problem. we had an incompatability between RH and the drives we were using.

Since my servers are at a colo, I never did know exactly which drives we had, suffice to say they where two 120GB drives. Not RAID format.

Apparently it was the thrashing that occurs during the cron hours, pushed an inode count way to high and then RH would crap out once the drives were accesses after the inode count was way up there.

So, we dropped in two 80GB drives from a different manufacturer and all has been well with over 89 days of uptime.

Thanks to everyone who contributed.
