Mailmanctl has found an existing lock file, extracted a pid from it and
is trying to signal that pid to see if it is still running. The signal
attempt is being denied by the OS.

If you're sure no mailmanctl is running, you can just manually remove
the locks/master-qrunner* files (you could first check the pid with ps
to be sure) as a workaround.
