py-setproctitle on FreeBSD 12.2 does not call setproctitle because its initialisation fails at some point. See https://github.com/dvarrazzo/py-setproctitle/issues/94
As a result of not setting the process title, you'll see failing service commands; In my case, for example:
$ sudo service -j mercurial-web hgweb restart
hgweb not running? (check /var/run/hgweb/hgweb.pid).
Hi, thanks for your report, I'll have a look and will investigate.
