While upgrading to the latest virtualmin with apt-get I noticed an error:
Warning: Module Configuration problem detected: The mailman program /var/lib/mailman/bin/mailman was not found on your system.
Webmin server did not write new PID file
(I will look at the mailman config, though it should work out of the box wich is not the case - that would be a different bug report I guess)
after that it completed the install normally, I tried
/etc/init.d/webmin stop and got the following:
# /etc/init.d/webmin stop
Stopping Webmin server in /usr/share/webmin
/etc/webmin/stop: line 4: kill: (30829) - No such process
/etc/init.d/webmin start returns no errors, neither does any subsequent start (without first stopping) webmin is NOT UP, it times out. Any subsequent stop returns the same error with the same pid number.
I am DOWN until this is resolved!
