Anyway, fail2ban is > no longer running[*], so let's restart it: Hi Frédéric, yeah -- thanks for filing and confirming the issue on a sid box -- segfault issue is known to fail2ban upstream https://github.com/fail2ban/fail2ban/issues/844 and I have reported it against sqlite3 in debian (CCed with this as a confirmation of replication on sid): https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=771341 There is some anecdotal evidence that recently merged upstream https://github.com/fail2ban/fail2ban/pull/839 might somehow be a workaround for the segfault. > # service fail2ban start > [....] Starting authentication failure monitor: fail2ban[....] Socket file > /var/[FAILail2ban/fail2ban.sock is present ... failed! > failed! > Yeah, I doubt it had the occasion to remove the socked file before > segfaulting.
