Investigating Intermittent Memcache set/add Failures in PHP Memcache Extension 2.2.7

The intermittent set/add failures observed with PHP’s Memcache extension 2.2.7 are caused by its built‑in 15‑second retry interval (MMC_DEFAULT_RETRY = 15) that marks the connection permanently failed after a poll timeout, and can be resolved by specifying the hidden fourth ‘timeoutms’ parameter, adjusting php.ini, or migrating to the newer Memcached extension.
