already performing on port 4567

[MilesTogoe]

running in development mode with webrick I sometimes get stuck with this
error msg:
already performing on port 4567 which prevents restarting the server

It seems like it occurs when I accidentally switch users without killing
(cntrl c) the server or maybe it's just a leak when starting, stopping
the server numerous times.

sans restarting my linux instance, is there someway to clear or kill the
running instance with webrick ?

Use ps to find the process id, and kill to kill it?

thks, I also found that simply "ps aux | grep ruby" gives the pid's and
a simple kill <pid> seems to clear out the processes.

You can try "lsof -i :4567" to find which process has the port open,
then stop it with kill.
