Problem after update to 1.8.0.beta10 (today)

The docker container is up.

My best guess is that the unicorn process is the issue:

Here is the bottom of docker logs, followed immediately by a ps -ef|grep unicorn

ok: run: redis: (pid 47) 688s
ok: run: postgres: (pid 44) 688s
supervisor pid: 3743 unicorn pid: 3748

I’ve done a(nother) ./launcher rebuild app, as well as a reboot in the meantime.

Could it be that the unicorn is falling over on it’s own before the start tries to kill it off and restart it, and the pids are getting out of sync?
