My remote ubuntu server is booting sporadically! What to do? [closed]
If it's rebooting spontaneously, that's either a hardware problem or a very, very strange malware infection. Hope as much as you want, but I'm betting it's dead. Protip: don't use desktop hardware for a server you need to rely on.
Well check the syslog for errors and see what it gives, maybe there is somekind of hardware failure causing kernel panick. In your shell use :
tail -f /var/log/messages
It will show all messages dynamically being added to the tail.
