Recently we received a user complaint that they were unable to access a server through vncviewer.
When I checked I found that the service was not running and when I attempted to start the service I got the below message:
[root@pbox bin]# /etc/init.d/vncserver start

[ OK ]
I wasn't able to query the status of the service either:
[root@pbox init.d]# service vncserver status
Xvnc dead but subsys locked
This error pointed me to the /var/lock/subsys/Xvnc file which I removed and then restarted the service but it did not work.
If I attempted to stop the service then that also did not succeed in the first attempt.
[root@pbox ~]# service vncserver stop
Shutting down VNC server: 1:vncuser 2:vncuser [FAILED]
Although it did work the second time I tried.
[root@pbox subsys]# service vncserver stop
Shutting down VNC server: [ OK ]
When I checked the /var/home/vncuser/.vnc/private.key I found it to be empty.
[root@pbox .vnc]# ls -l private.key
-rw------- 1 vncuser vncuser 0 Oct 5 04:12 private.key
I restarted the vnc service multiple times and even installed realvnc again but that did not work. According to the documentation I found on realvnc, the private key should've been regenerated after a restart of the service or created at least when I re-installed the software but that did not happen.
I finally ended up copying the private key from a server on which realvnc was already running and started the service on the problematic server and it finally worked.
[root@pbox ~]# service vncserver restart
