FWIW, I may have found a resolve by adding the following to /usr/local/apache/conf/httpd.conf
SSLSessionCache memcache:127.0.0.1:11211
LoadModule socache_memcache_module modules/mod_socache_memcache.so
Technically I simply removed the '#' from LoadModule socache_memcache_module modules/mod_socache_memcache.so within the /usr/local/apache/conf/httpd.conf file.
Apache restarted without the error and yes, I do have memcached enabled and configured on the server; including PHP support for three (3) switchable PHP versions.
The next question is there any benefit to using memcache as opposed to shmbc in reference to SSLSessionCache and does this make any difference being that I'm not loading mod_ssl.so, as I understand SSL support is provided via OpenSSL? (Yes, my site uses SSL via Let's Encrypt Cert., FWIW).
Your thoughts and suggestions are highly welcomed!
Thanks!
