NW 6.5 sp8 - server sudden reboot

[jselaya]

Hi

We have a NW 6.4 server with sp8. Approximatly 4 days ago the server suddenly rebooted. The server is working just fine since the reboot however I would like to determine the cause of the reboot. I checked the error log but was not able to see any message that can explain the cause of the reboot. I also setup e-mail alerts for server health when CPU utilizations exceed 100%. I did not recieve any e-mail notification prior to the reboot. Can you recommend some additional steps I can try to help me find out why the server rebooted.

Any help you can provide will be greatly appreciated.

Thanks for your time.
Jose
