The files 'master-qrunner' and 'master-qrunner.host.pid' are not list
locks. They are the lock that prevent starting mailmanctl when it's
already running.

Are there entries in Mailman's smtp-failure log?

Is there only one listname.lock file and two listname.lock.host.pid.seq
files? If so, one pid has the lock and the other is waiting.

Do the timestamps and other things about these lock files change over

I'm not sure why the above trace is logged at all, but I don't think is
is significant.
