Hello Oliver Welter, Thank you for the report. You haven't posted exact warning that you are seeing but knowing the behavior in previous issues I can assume it is a "Note" i.e "[Note] While initializing dump thread for slave with UUID <xxxxx-xxxx-xxx-xxxx-xxxxxx>, found a zombie dump thread with the same UUID. Master is killing the zombie dump thread(<number>)" Post Bug #72578 fix, a NOTE is added on master's error log file when log_warnings is greater than 1. Please see the detailed explanation in Bug #84358 by Sven Sandberg, he explained the cases in which this "Note" is observed, and why this is expected behavior. Thanks, Umesh
