Cannot Start xserver

[Kalyan Sundar]

Hi All,
We are trying to unzip a huge file on our Linux server.
It is progressising without any issues but after 2 hrs I get below error.

Cannot Start Xserver (your graphical interface) It is likely that it is not
set-up correctly.

Please advice to resolve such behavior of Linux.

Note : We are on RHEL AS 4 .

Thanks,
Kalyan
