Hello,
After the recent MariaDB 10.1.41 update which happened on 01/Aug/2019, few
of our slaves have stopped syncing relay logs from master which is on
10.1.40. Slaves which got automatically updated to 10.1.41 is now having
the following status. Slave IO thread is in Preparing state and the logs
are not getting written. I did a reset slave and initiated a change master
with the positions again but still getting the same. The other slave
servers which is in MariaDB 10.1.40, 10.1.33 etc are running as normal.
These which got upgraded to 10.1.41 has issue?
Does anyone have any clue on this?
