Hi one of our Linux machine from our Data Farm have constantly hang and instable. I found out from the console the below error. Does anyone encounter this problem or see this error before with a glimpse on what it could be.. ?

After the troubled time at last i managed to get the answer. The System CMOS time is un-synced with the ntp time of the system. This is caused by the CMOS. After checked the /var/log/messages i found the ntpd died after the above error's reflect. And this causing the system to hang.

Changed the CMOS battery solved the problem... Unhappy ending
