I'm seeing the same issue, and on my system it consistently coincides with the
Exim log file being rotated. This means that fail2ban will work until the end
of the day and then needs to be restarted.
Package: fail2ban
Version: 0.11.2-2
Severity: important
Hacker tries to guess user password on SMTP -- Exim4.
Then fail2ban stops blocking him, because it thinks there are "Too many errors".
This is not the case -- there are errors, because hackers are attacking.
I restart fail2ban manually
