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. The information in this e-mail is intended only for the person to whom it is addressed.
