VNC Restart needs pause between Stop and Start
Last modified: 2007-04-18 12:51:29 EDT
Description of problem:
When /etc/init.d/vncserver is invoked with "restart" or "condrestart", it runs
its "stop" procedure and then its "start" procedure. In most init scripts, this
behavior is fine. However, in the case of vncserver, a directive to shut down
the vnc server instances might not be instantaneous.
I suggest a "sleep 10" between the "stop" and "start" lines as a quick fix.
Better might be to explicitly wait for the servers to exit.
How reproducible: Very
Steps to Reproduce:
1. Configure vncserver init script to start a session
2. Connect to that session
3. From another login, invoke /etc/init.d/vncserver restart
4. Observe that although the vnc session goes away, it does not get restarted.
Since the VNC server has not yet completely exited, it appears to already exist
when the "start" is invoked. Naturally, "start" fails to invoke another
instance. When the "stopping" instance finally goes away, there is no VNC
server for the user on that system, until either reboot or other invocation
of "/etc/init.d/vncserver start".
Existing VNC servers go away. New instances of the configured VNC servers are
This was observed on a fairly fast P4 system. However, I suspect that the more
things are running within the VNC session(s), the more likely this result will
