Description
Please create some documentation specifying possible error/failures to operations, what they "look" like in the logs/exceptions/stack traces and what our recommendation is on how to handle them.
i.e. tmp_oom, timeouts (connection/operation/java-internal/etc), "get miss" (it's technically a failure, let's make it overly obvious what it means), CAS failure, add() failure, replace() failure,
Some of this should be covered in the API reference, but this bug is specifically for a single page where this information is aggregated that a customer/user could read about how to handle errors.
