I use repcached for session and data redundancy.
For some reason, version 8.2 is slow to load modules and sessions.
I found that there was a timeout when connecting to the memcached server when executing "php -i".
Here is the memcache server log.

Log

"php-repcached-issue-memcached1-1" is fine.
But "php-repcached-issue-memcached2-1" loops until it times out.
