And 8 runners were started.

Then the next morning Mailman's logs were rotated.

You haven't shown 'cat qrunner', but it presumably is just another
logrotate set like 'cat  qrunner.1' only a day later.

The strange (interesting?) thing is all of qrunner.4.gz through
qrunner.7.gz are gzips of empty files. logrotate ran because the log was
rotated, but no SIGHUP entries were written.

My best guess is this is because Mailman wasn't running between Aug 23
07:58 and the reboot time and probably for some time before that which
is why messages were just queued and not processed until you rebooted
which started Mailman.

If you have no older Mailman logs, we don't know why or exactly when
Mailman stopped, but I'm reasonably sure that's what happened.
