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?

I've run into similar, though not identical, issues when a machine is
part of an active directory domain. Apparently, authenticating off the
domain controller.

Has there been any change in authentication methods, or joining a
Windows domain, or anything similar?

off. Vampires get dates. Hell, even the school librarian sees
more action than me.

Hello --

That apparently was the problem. The domain controller used by the system was offline for several hours.
Once it came back on-line, the lag that I described in my posting was no longer present.
