I have fail2ban running on my Asterisk box.
Every so often I receive emails stating that the jails stopped and then started.
Why does this happen?
Why isn’t it just continuously running?
fail2ban is restarted when it switches its log file. Depending on
your platform, this can be the result of a cron job, an entry in
/etc/lograte.d, /etc/newsyslog.conf, whatever. It’s normal.
