title: MySQL / phpMyadmin: "many connection errors"
body: <p>My app no longer connects to its DB and phpmyadmin says #1129 - Host 'xxx.xx.xx.xx' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'</p>
  
  <p>mysql_error() prints out the same message. Could this be because of too many connections?</p>
  
  <p>What causes this?</p>
