sometimes my memcached server returns the following error:
Zend\Cache\Exception\RuntimeException' with message 'SERVER FAILED TO ALLOCATE OBJECT'
Can anyone explain what this error mean?
Problem solved. The memcached memory was full, the error message was a little bit confusing...
When there is no more space in memcached, you get this error.
To get Memcached total usage:
>> echo "stats" | nc 127.0.0.1 11211 | grep bytes
To flush the memory from your memcached server, you can do this from your CLI
>> echo 'flush_all' | netcat localhost 11211
>> sudo service memcached restart
