A vnc server is already running as 2 failed

I am  using vnc on my Redhat 5.8 box. I used "service vncserver start" to start vncserver at startup. But when I try to connect to "myhost:2" using vncviewer on another machine, it failed.

 When I type "ps -ef|grep vncserver", I couldn't see "vncserver" running

Error Detailed:-
