On checking the process, Xvfb is not running.
[root@NSMXpress errorLog]# ps auxww | grep Xvfb
root      7592  0.0  0.0  5100  648 pts/1    S+   23:35   0:00 grep Xvfb
Solution:
Make sure to install the necessary system update file, before upgrading NSM. Execute /usr/X11R6/bin/Xvfb -pn :991.0 &.

Verify if Xvfb is running:
[root@NSMXpress errorLog]# ps auxww | grep Xvfb
root 7592 0.0 0.0 5100 648 pts/1 S+ 23:35 0:00 grep Xvfb
nsm 27973 0.0 0.0 9072 3504 ? S Jan08 0:00 /usr/X11R6/bin/Xvfb -pn :991.0

Reboot the NSM server, if you have upgraded or installed NSM.
