I am running MySQL 5.5.31 on FreeBSD 9.2. I have a web server with a miss-configured service that generates faulty connections. After a while, MySQl blocks any connection from the web server.
At some stage, I had set-up a script that would browse syslog log and look for a string like "Host 'xxx' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'" and would then issue a mysqladmin flush-hosts.
But after an upgrade, MySQl stopped reporting to syslog. Any help will be greatly appreciated.
