HPUX 10.20 - Warning! One or more of your selected locales are not available.

On our system a user successfully ran the only application on the system this morning. When they tried to login a bit later they could not. The Admin tried to reboot the server and it seemed to reboot ok. When logged in the admin tried to change directories and gets the below message (note they also ran locale as instructed). Is this a hardware or software issue?
Thanks...Joe
