Hi,
looking at the log there has been a lot of power failures. Was that you hard resetting the machine or actual power failures.
If it was actual power failures, follow the instructions in the log (check plug,..., check power supply).

Also seems your seagate disk at 0/0/1/1.0.0, may have suffered with the power re-sets. One of the messages refers to:

Have you had any changes to the system ?
Where is the machine currently hanging ?

hi,

Actually machine is running with one power supply. others are free, thats why that error is coming... there is no particular time of hanging. oracle database and SAP application is running on that machine. suddenly application was not working, checked the server, i got ping reply but i cant connect thru telnet or ftp.

Hi,

Is /var/tmp and /tmp having enough free space ?
Any errors in syslog ?

Hi,

It appears that you have a faulty PSU and a faulty root disk. It's possible the faulty PSU caused or at least aggravated the disk problem. In any event, either fault could have caused your server to hang. Both need to be corrected.
