If you get the following error, it means that mysqld has received many connect requests from the host 'host_name' that have been interrupted in the middle:

9R w:zbmMJ0The number of interrupted connect requests allowed is determined by the value of the max_connect_errors system variable. After max_connect_errors failed requests, mysqld assumes that something is wrong (for example, that someone is trying to break in), and blocks the host from further connections until you execute a mysqladmin flush-hosts command or issue a FLUSH HOSTS statement. See Section 5.2.2, “Server System Variables”.
