It seems because the jail starts at each boot running syncthing again, the host system rebooted each time it started the jail. A vicious circle. Because of this, I was nearly unable to connect to the server. By continuously pinging the server and sending a ssh ezjail-admin config -r norun once I knew the server is online again, I could stop the circle and finally log into the server again. I guess that something's wrong with net/syncthing (or its configuration) but what worries me more is how a malfunctioning jail can cause an entire host system to reboot? Thanks for your help and best, -- Niklaas
