Topic: Critical error in memcached 1.4.18 using old version of libevent
Somehow version 1.4.18 of memcached in remi, which was just released was built with or using a version of libevent that is super old.
➜ ~ telnet 127.0.0.1 11211

STAT version 1.4.18
STAT libevent 1.4.13-stable
Notice libevent 1.4.13. I did yum downgrade memcached and it shows:
memcached 1.4.17
and
libevent-last 2.0.18
If you downgrade to memcached 1.4.17 and do stats, it shows it using libevent 2.0.18.
This is a critical bug. I spent the last week back and forth with the main contributor of memcached trying to debug timeout issues and runaway 100% cpu on a memcached thread.
