Yesterday something strange started happening to our Web Server, it started becoming unresponsive and we could not remote into it. Only every few minutes we can make a connection to be booted off again.
So we started digging into the log files of the remote servers and found some interesting stuff.
Now what you see above is a very abridge snippet of what we saw, the first two were repeating every second, and then after 20 minutes of that every single second the third message was coming up, for hours.
Now we were able to resolve this issue by simply clearing the hosts and restarting our MySQL service. But whats really strange is we did not change anything and nothing is "new" its as if one of our Remotes decided yesterday was the day to smash the Web Server with MySQL connection attempts.
Any ideas on what caused this and how to prevent this?
