note 111293 added to memcache.set

What are the cases where set function returns false? I've an object that when passed to set function, some times I've to try to set it once and twice and three times before it got set. Sometimes from first time it set it successfully, but most of time I've to try to set it more than once before it got set. ---- Server IP: 69.147.83.199 Probable Submitter: 94.127.209.4 ---- Manual Page -- http://php.net/manual/en/memcache.set.php Edit -- https://master.php.net/note/edit/111293 Del: integrated -- https://master.php.net/note/delete/111293/integrated Del: useless -- https://master.php.net/note/delete/111293/useless Del: bad code -- https://master.php.net/note/delete/111293/bad+code Del: spam -- https://master.php.net/note/delete/111293/spam Del: non-english -- https://master.php.net/note/delete/111293/non-english Del: in docs -- https://master.php.net/note/delete/111293/in+docs Del: other reasons-- https://master.php.net/note/delete/111293 Reject -- https://master.php.net/note/reject/111293 Search -- https://master.php.net/manage/user-notes.php
