PHP 8.0.20 fpm pool keeps restarting, FreeBSD 13, with Apache 2.4

Hello,

I'm running Apache 2.4 on FreeBSD 13. I was running PHP 7 then decided
an upgrade to 8. Ever since then I've not been able to get my test php
script to work. Checking the logs both Apache error and php-fpm it is
looking like the php-fpm process is dying then respawning, atempted
connections take a while then eventually time out with a 503 message.
The below is debug log from php-fpm.log while atempting a connection
to the info script.

#service php-fpm start
Performing sanity check on php-fpm configuration:

The rest repeats. Apache gives me an error dispatching message given
how hard fpm is working I'm not surprised it's timing out.
