REAL VNC installed on RHEL 5.9 keeps restarting
I have installed Real VNC 5.2.1 on several RHEL 5.9 servers, nine to be exact. On eight of the installations, all works fine. However, on one installation I noticed it was working for 5 -10 seconds and then unavailable for the next 5 -10 seconds.
Troubleshooting:
using 'ps -ef | grep vnc' I was watching the loaded modules.
The normal return as such:
root 13211 1 1 Nov13 ? 00:17:05 vncserver-x11-serviced
root 13237 1 0 Nov13 ? 00:00:00 vncserver-virtuald
root 20572 13211 0 10:20 ? 00:00:00 /usr/bin/vncserver-x11-core -service
root 20623 20355 0 10:20 pts/1 00:00:00 grep vnc
Then periodically it returns:
root 13211 1 1 Nov13 ? 00:17:06 vncserver-x11-serviced
root 13237 1 0 Nov13 ? 00:00:00 vncserver-virtuald
root 20965 13211 0 10:20 ? 00:00:00 [vncserver-x11-c]
root 21364 20355 0 10:20 pts/1 00:00:00 grep vnc
At which point vncserver-x11-core relaunches and ~20 seconds later it is
Also watching the ports Real VNC is using by issuing 'netstat -nap | grep vnc' for the period VNC is responsive you see:

And during the periods it is NOT responding you will see only:

I have removed and re-installed Realvnc 5.2.1 at least twice. I have configured exactly like the other eight servers that are working correctly. What further steps can I take to troubleshoot this issue?
