On several of my 2.3.8.1 servers postscript just stops. I try to start it but it fails. A reboot usually works. Changing permissions to 755 on /var/lib/postfix/master.lock doesn’t help.

journalctl -xe

Update. Just killing postfix via kill -9 $(pgrep master) then lets me start postfix. Should I include this in a script I have running daily to start postfix in case it isn’t running?
