Hi all

An issue (like unstable accesses to servers and services are down) occurred on a server after the following error was output in "/var/log/messages".

That kernel is more than two years old. See if a newer kernel works better. Try yum update.

There are more than 31,000 lines in the kernel rpm changelog since the one you are running. That's 31,000 bug fixes you do not have...
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.
