Remember reading about that, and on the server I happen to be looking at, it's been set that way since 18 May. Any other ideas?
The first thing I can think of is you forgot to restart the service after making the configuration change, but then you mentioned restarting the service makes the issue disappear, so that's not it :) .
Perhaps you are seeing machines that only make a single attempt between log rotations? Or perhaps your machines get so many connects that you've hit a resource limit in fail2ban? Just guessing, I haven't had any issues since changing the backend to gamin.
Don't think so. I just dug up one that happened over the weekend: greping out the lines from secure, I've got 131 connection/disconnect pairs: Aug 10 17:44:56 <my server> sshd[12350]: Connection from 114.113.199.142 port 511 871 Aug 10 17:44:57 <my server> sshd[12341]: Received disconnect from 114.113.199.144 2: 11: Bye Bye
Yet in messages, all I see from this server (it happens to be our loghost) for the entire minute of 17:44 are ordinary DHCP messages.
