It appears that dc_errors is empty despite a retention policy of 1000KB memory, 10GB(~) disk,
I noticed this on 2 different clusters running 7.1.1-x versions . The collection process restart after rerunning the
SELECT SET_DATA_COLLECTOR_POLICY('Errors', '2000', '1000000'); with the same parameter.

The data collector table shows no records and a lot of retired files. This behavior is not according to data collector design in my opinion. Is this a bug in version 7 ?
