Motivation

Generally, we have many instances of the same application (for load balancing) and sometimes different applications sharing a single Memcache data source.

In these scenarios, the checks randomly fail, depending on the order of get, set, delete competing between all instances.

Proposal

Use unique keys when accessing Memcache.
