I have recently been upgrading a set of config managed servers from Ubuntu 14 -> 16 -> 18
This required upgrades to nginx/passenger and lxc (from 2 to 3.0.3)
Having updated my lxc containers’ configs, most things are working nicely but there is one unexpected problem in that the containers are destroyed on all but 1 server when nginx is restarted.
The difference between the 1 “working” and other “failing” servers appears to be an entry in the journalctl:
nginx.service: Killing process 13743 (lxc-start)
As far as I can tell, all the relevant configs (nginx,passenger,lxc) match and I have ran out of ideas of where to look next.
Has anyone else run into (and hopefully solved) into this issue? I am sure this must be a config issue somewhere but I am not sure where else to look so any advice will be greatly appreciated.
Phusion Passenger: 6.0.2
OS: Ubuntu 18.04.2 Bionic Bear
