The service was not gracefully stopped the last time it was running and
left the master lock behind. The FAQ at
<http://wiki.list.org/x/17891756> describes how locks are implemented in
Mailman 2.1, but Mailman 3 is similar.

There is a var/locks/ directory in your Mailman hierarchy. In it you
will see two files. in MM 2.1, they would be named master-qrunner and
master-qrunner.hostname.pid. In MM 3 they will be similar. Assuming
there is no process with PID = pid running on hostname, you can safely
remove those files.
