Fail2Ban restart

I've got Ubuntu latest distro + fail2ban (latest) - box running basically just asterisk + Lamp
I had a problem with fail2ban endlessly starting every 2 mins.
Assumed it was the result of a brute-force attack.
Did a re-install, everything hunky-dory 48hrs, now its started again (restarting every 2mins), anybody?
Is this some new vulnerability?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Have you checked the logs?  That might give you a clue to what could be causing it.

If you suspect an attack, check firewall logs.
Maybe you have greedy logrotate.
Why dont you install official fail2ban from Ubuntu? It has everything pre-configured.

does systemd restart your services over & over..??
the classic init syste, does not do that.
