Hi,

You should review OS patch levels thoroughly, run the available OS diagnostics and consider replacing some hardware if necessary.
Contact your HW vendor and run the HW Level diagnostic.
perhaps, hard drive is going bad.

Have a look to see where and if smartd is being used on your system.

# man smartd

usualy the file /etc/smartd.conf will is where the smartd environment is set up

'usualy' this send it's error message to /var/log/messages ... in your case it may be sending elsewhere !

Re: hard drive going bad ?

Matter discussed with DBA. As per him this is logical block problem , not physical block problem. Still to be on secure side hp offline diagnostics will be run.
