Possible successful read of a key that didn't exist in the kvp store.

I had an anomaly occur on 2014-11-26 at 22:25:58 where I suspected a successful read occurred for a key that did not exist in the kvp store instead of a failure and error code return.

I believed the data returned by the data server was "1," where a success was determined but no additional data was returned.

This operation typically takes a fraction of a second to run, but at that time I was getting repeated timeouts for reads for over a 15 second period of time with 3 seconds allotted for a timeout.

This blank data crashed a processing script further down stream.

I'm now including additional debugging and checks to look for this anomaly to occur in the future.

Did anyone have any of their kvp apps behave strangely during the same time?

Has anyone seen any undocumented behaviour with the kvp store functions?

I had another successful read with blank data occurred again at 2015/03/27 23:26:10 in the region, Shiromani.

"1," was returned instead of including the data from the key.

A second read attempt returned data.

So everyone should be aware that it is possible for a successful read to return no data for a key value that is not an actual null string.
