Secondly what causes this alarm to generate and are they threatening?? Thirdly currently we are planning to reboot the server so what precaution we should take against these error.
As you've been told before in a few of your other threads, you need to contact Red Hat support, since you're PAYING for RHEL. As JohnVV pointed out, even now you're in a totally unsupported
environment, probably due to your company NOT PAYING FOR RHEL
, and not getting the patches/updates you need. If you're going to use Red Hat Enterprise, then you need to PAY FOR IT.
Chances are you're getting errors because your system is old, unpatched, and unupdated, and there is some sort of error in there. flyinggeorge pointed out some issues, but you also posted two OTHER threads about disk problems:
...and were told VERY explicitly to back up your data, replace the disk, and reload. This is STILL the best advice, especially given your old, outdated OS. So, PAY FOR the latest version of RHEL (6.x), and load it, or load the free version of CentOS, restore your data from backup, and move forward, after you replace the bad hardware.
