CentOS - Jun 2012 - Hanging issue with sudo command

Hello --

We are running Centos 5.2 64-bit on a system that functions as a mail server,
and also runs a virtual server via the Virtualbox application.
A user account was given sudo access via the sudoers file several years ago, and
that account has worked well with various administrative
jobs on the server.

Recently it was observed the user account took longer to complete its login from
a terminal window and console. It is also now having
problems when running the sudo command. Essentially when the user runs the
command, the latter hangs, and the administrator is
forced to log in as root, and kill the hung progress.

What would cause this issue to occur, and how can it be corrected?

Thanks.

Update that to current and see if the problem still occurs...

It might well be down to some bug or other over the last 3 to 3 1/2 years...

Any recent changes to DNS settings on server?
