Linux server halting every few days

  • 772

Our Linux Server keeps getting the following message every few days. Where would I go to track down this issue?

Broadcast message from root (Mon Mar 1 20:13:57 2010):

The system is going down for system halt NOW!

Edit: /var/log/messages looks like this

Mar 1 18:10:05 CFMC2 sshd(pam_unix)[3326]: session closed for user alberte

Mar 1 20:13:57 CFMC2 shutdown: shutting down for system halt

Mar 1 20:13:57 CFMC2 init: Switching to runlevel: 0

Mar 1 20:13:57 CFMC2 gconfd (cfmc-5252): Received signal 15, shutting down cleanly

Mar 1 20:13:57 CFMC2 gconfd (cfmc-5252): Exiting

I also just foound this after running the command 'last'

reboot system boot 2.6.9-67.0.1.ELs Mon Mar 1 20:41 (15:35)

Thanks, Digital Ninja

    The last time I saw this it turned out to be a bad motherboard sensor. The sensor was convinced the server was overheating and the OS would just shut down.

    Check your BIOS or built-in management for hardware event logs that might describe what is happening.

  2. Dude, someone has put shutdown -h now into crontab.

    Check /var/log/cron

  3. Is there a UPS attached to the machine? Are you sure it's not telling the machine to shut down because it thinks it's dying?

  4. Couple things:

    • Who has access to this box? Check to see who logged on during those times and check the shell history files.

    • Have you checked out the log files for anything strange?

    • What do you have running on this box? Anything particular happening when this occurs?

    • Any time similarities to when this happens?
