How to Troubleshoot Sudden Server Restarts
Hi guys,
Hoping someone can help me troubleshoot a server that keeps restarting suddenly. Its a Ubuntu SMP 3.0.0-12-server x86_64 GNU/Linux server which hosts Samba services for multiple remote IIS web applications. Users have been reporting that services are failing throughout the day and a quick system check seems to validate that the server is indeed restarting. Code:
developer@knoxfactoryfs011:/var/log$ last reboot|head -1 Code:
developer@knoxfactoryfs011:/var/log$ who -b Can anyone provide clues as to how I might troubleshoot something like this? |
Hi
Did u check out these log # tail -f /var/log/wtmp # tail -f /var/log/message ----- u can find the cause of reboot over these log check whether u had enabled any crontab schedule for reboot . |

There doesn't seem to be any message what so ever of an initialized shutdown -r in syslog but you can definitely see where the machine started (just not shutdown). syslog Code:
May 8 07:17:01 knoxfactoryfs011 CRON[10746]: (root) CMD (cd / && run-parts --report /etc/cron.hourly) kern.log Code:
May 8 09:20:36 knoxfactoryfs011 kernel: [0.000000] Calgary: Unable to locate RioGrande table in EBDA - bailing! |
If it were the OS, you would have error messages logged.
It's a hardware problem. Hopefully the server vendor has good warranty support because you will need it to isolate the offending component. (power supply interface, mainboard issue, powersupply itself) |
