    Description

      Hi There,

      We've observed the GTID value within current_gtid.txt is behind what is reported by the maxctrl CLI. We have three Maxscale instances, the current_gtid.txt on each one exhibits the same behaviour. The value within the current_gtid.txt files is at least a day old, yet the binary logs are purged after 3 hrs.

      Thanks.
