Thanks [vaibhav\_upadhyay40](https://forums.percona.com/profile/vaibhav_upadhyay40) . We are seeing below messages in error log file only after applying 5.7.30 patch.

I have seen tens of millions of those over the years Ive researched and looked and tried everything… Ive never been able to get rid of them as it is only a NOTE vs a warning or anything else I have just ignored them
