Problem:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268318

When running apache with php, using "apachectl graceful" will cause http to core dump.
Anything such as certbot and logrotate which uses apachectl graceful will kill httpd.

FreeBSD-13.2
apache24
php81
php82


Cause:

php opcache extension is installed

php81 /usr/local/lib/php/20210902/opcache.so
php82 /usr/local/lib/php/20220829/opcache.so


Remedy 1:

Disable ASLR in /etc/rc.conf

apache24_aslr_disable="YES"


Remedy 2:

Remove any php opcache extension that are installed. (you probably do not want to do this)

pkg remove php81-opcache
pkg remove php82-opcache


Remedy 3:

Keep php opcache installed and never use "apachectl graceful", which is hard to remember.
Hunt down any scripts that use it, make a backup, and change it to use "apachectl restart".
Remember that graceful exists because it is not the same as restart for good reason.

logrotate: /usr/local/etc/logrotate.d/apache24
certbot:   /usr/local/lib/python3.9/site-packages/certbot_apache/_internal/configurator.py
