Fail2ban

(taken from askubuntu)

"There's a (seemingly) faulty fail2ban script that apparently 'runs too quickly', so I found a workaround.

Quoting: I had multiple fail2ban.action.action ERROR on startup/restart. It seems there was a "race" condition with iptables. I solved the problem completely on my system by editing /usr/bin/fail2ban-client and adding a time.sleep(0.1):"

def __processCmd(self, cmd, showRet = True):
    beautifier = Beautifier()
    for c in cmd:
        time.sleep(0.1)
        beautifier.setInputCmd(c)
