after i switch caching metadata from Phalcon\Mvc\Model\Metadata\Memory to Phalcon\Mvc\Model\Metadata\Apc, it shows some columns do not belong to this model. i try to dump metadata both apc and memory and found apc miss some columns. after i clear apc cache, and it works.....
so.... is this a bug? the follwing is my apc.ini configuration
apc.ttl 7200
apc.user_ttl 7200
apc.gc_ttl 0 <= will it be cause the problem?
