    Same kernel.
    However I have only one jail. How many jails do you have? Does it
      start if you reduce the number of jails? Have you seen this:
      https://github.com/fail2ban/fail2ban/issues/969 Unfortunately the
      bug is still open...

          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.
          

          What release/version?
