Fail2ban extension hangs

[Paula1]

Hi there,
I just update to 12.0.18 Update #69

Suddenly Fail2ban extension hangs and uses a lot a ram when I try to see the banned ips.

I have the same symptoms explained in this article http://kb.odin.com/en/122407
I don't use any big jail. I use only proftp, sshd and recidive.
Although I'm pretty sure the solution that they provide does not applied to my situation, I tried it without any luck.

I tried the following as well:

-disabling all jails,
-restarting the server,
-uninstalling and reinstalling fail2ban (using add/remove components)

The problem persists even without any jail activated.

I will appreciate any help,
Thanks in advance.

What version of Fail2ban are you running?

fail2ban-client -V

If you are running 0.9.3 you should see the following posts (Plesk 12.0.x and Fail2ban 0.9.3 don't play nice)

I ran into the same problem. I have uninstalled Fail2Ban, excluded it from the EPEL repo and reinstalled Fail2Ban via the Plesk installer.

Everything is now working ok again

Thanks both of you for your help.
The problem is solved:

-uninstall fail2ban
-exclude fail2ban from EPEL repository
-reinstall fail2ban using plesk installer.

Just like Cris1 said it. (I appreciate Gbotica's helps as well)

Thanks!
