What is the optimal value for max_connect_errors?

Question

MySQL

Actually, what value should be set and what threatens too large a value, they write differently everywhere, someone puts 1000, 10000, 1000000, etc.

Answer 1

This setting is quite pointless, set a lot and monitor aborted_connects/aborted_clients.
Since the problem with aborted connects usually does not arise out of the blue.
Well, reset once a day via flush hosts, for example.
