I'm getting the above error as soon as I enable Memcache at my Drupal application.
- Memcache is within the same environment as Apache
- PHP version 5.5.0
- "extension=memcached.so" added to php.ini
- Error doesn't appear on local dev environment
- Error doesn't appear on another VPS
This issue may be related to an outdated libmemcached version: https://serverfault.com/questions/456300/upgraded-php-to-5-3-19-and-memcached-stopped-working
Is there anything I can try?
