So! This is not nice!

I had 12 jails working before. I rewrote my private jail.config, didn't help. Changed it in default jail.conf (should'nt), enabled 2 jails - working. huh?

Reworte again my private config in jail.d with 2 jails, working. Based on try and error, i confiirm for me, that 7 jails are working flawlessy, from the eight on, it gives back the error-message. Can anybody confirm this?

Clear bug for me!

hi, thanks, yes i saw the bug, even if its quite old. i didnt find where to change that number. i have 7 jails, none of them is starting, just one main thread, which does not seem to be a jail. the service is running as yours does. but there is no jail at all, i think, as i get no mail notification about any jail. i use mail notification, do you?
I do get mail notifcations and my jail/s work. my /etc/fail2ban/jail.local looks like the following [DEFAULT] findtime = 86400 bantime = 86400 banaction = firewallcmd-ipset backend = systemd sender = <actual email> destemail = <actual email> action = "" [sshd] enabled = true I also have a few other jails enabled where appropriate. I have the following packages installed fail2ban-systemd-0.9.7-2.fc26.noarch fail2ban-server-0.9.7-2.fc26.noarch fail2ban-firewalld-0.9.7-2.fc26.noarch fail2ban-sendmail-0.9.7-2.fc26.noarch Dennis

Same kernel. However I have only one jail. How many jails do you have? Does it start if you reduce the number of jails?

Hi, is someone else experiencing problems? with fail2ban and systemd? Mine doesn't start the jails, client itself is running. Log says, it cannot create a separate child per jail.
