Debian Server Keeps Restarting Unexpectedly


You need to provide more information, especially log entries right before the system rebooted. However as far as I can see it may not provide more information. Check other logs such as syslog.

The most common causes in my experience for sudden restarts without any indication really of what went wrong is often hardware related. Otherwise the kernel mostly will have a chance of writing something in the logs to give a clue.

Some common causes of sudden restarts:

  • Overheating, probably the main cause, get an idea of the temperature, try to log it, does the server have a display that could show the temperature, is the room cooled properly. Perhaps replace the thermal compound on the heatsinks covering the CPU(s).

  • Bad hardware or drivers, get a list of it using "lspci" for example, a bad dimm can cause a system to suddenly hang and/or reboot (re-seat dimms, CPUs and cards). I remember a server which rebooted occasionally due to an issue with the intel ethernet card. Sometimes a bad disk can cause such problems as well, although normally it would just cause it to hang rather than restart.

  • A bad UPS, I remember a battery backed UPS going bad slowly and one of the indicators it did so was a regular weekly power cycle of servers connected to it. You could just have a mis-configured power cycle schedule.
