Thanks for sharing, i already search boot and syslog file in ubuntu. i am unable to find the issue.no serious error has been reported.
i ran the command " grep -iHR "(reboot|shutdown|restart)" /var/log but unfortunately i haven't found any eye catching entry actually the problem machine is ubuntu only, but i am also worried about my 90% debian end environment that i am running since 4 years .if some thing happen to those servers, what would be my options. this is what i am trying to learn from this guestio
