Confirm that it is running, and the log does update with debug messages, just see no sign of ban or unban taking place.

Excerpted from the fail2ban mailing list:
Upgrading to 0.8.8 solved the problem for me. It is entirely possible (and quite likely) that upgrading to 0.8.8 was somewhat of a "red herring". Perhaps the upgrade process simply reset something that was botched-up. Given that you are already on 0.8.8, I'm not sure what to tell you to try next. Have you gone to the fail2ban mailing list with this?
I haven't gone down the fail2ban mailing list route yet, wanted to see if anyone running more or less the same setup I am have experienced the same issue first.
Curious, what do you use for backend setting, it was set to 'auto' but I changed it to 'polling' and got no results
