The max_connect_errors system variable determines the number of successive\u00a0interrupted connection requests that are allowed. Once there are max_connect_errors\u00a0failed requests without a successful connection, mysqld assumes that something is wrong\u00a0and blocks the host from further connections until the FLUSH HOSTS statement or\u00a0mysqladmin flush-hosts command is issued.<\/p>\n\n\n\n

mysqld blocks a host after 100 connection errors as a default. It can be adjusted by setting\u00a0the max_connect_errors value on the server startup, as follows:<\/p>\n\n\n\n

This value can also be set up at runtime, as follows:<\/p>\n\n\n\n

It should be checked first that there is nothing wrong with TCP\/IP connections from the\u00a0host if the host_name is blocked error is received for a particular host. Increasing the value\u00a0of the max_connect_errors variable does not help if the network has problems.<\/p>\n","protected":false},"excerpt":{"rendered":"
