ZF-11544: Memcache seems to be offline
Sometimes, with memcache activated, it seems the memcache server is down.
An exception is thrown each times the problem occures "Can\'t get filling percentage."
The problem is in Zend/Cache/BackendMemcached.php The function php function getExtendedStats() is buggy and sometimes return false, even if memcache servers are online. The bug is declared here : http://pecl.php.net/bugs/bug.php?id=22158
If you can have only one memcache server, you can use this patch : //$mems = $this->_memcache->getExtendedStats(); $memsStats = $this->_memcache->getStats(); $mems = array($memsStats);
