front hangup on restart

[gizocz]

When front container restarts it logs only "Hangup" and does not start. How to reproduce: "docker-compose restart front" OR "systemctl restart docker" OR reboot the machine.

Problem is "nginx -s reload" in config.py. On the first run, it logs 'nginx: [error] open() "/var/run/nginx.pid" failed (2: No such file or directory)'. If the container restarts, the "/var/log/nginx.pid" exists, but the not the process, and "nginx -s reload" is the last command executed, "Hangup" is logged, and container exited with code 129.

Thanks for reporting, will fix urgently.

FWIW, it's still happening in v1.5.1 (not sure what version the fix on Feb 8 went into), but it just happened to me this afternoon.

As a work-around to get front running again (since it dies before I can get into the container and manually remove the pid file), I used this work-around:

1. Manually created a folder named 'pids' in the /mailu folder.
2. Manually added a mount to the front container in docker-compose.
3. docker-compose restart the stack.

Also, in fix #341, the fix looks to be removing and checking in /var/log/nginx.pid... is that right? Or, shouldn't it be in /var/run/nginx.pid?
