Here you go:

```

```

Oh wait, I just discovered the possible reason (but it shouldnt segfault anyway?).

I started my container without initialising the configuration (so no ctrl/ dir) - so it earlier complains about:

```
3/1 21:42:58 term !ERROR loading configuration files: ERROR 2 (No such file or directory) opening /opt/sbbs/ctrl/main.ini
3/1 21:42:58 term Terminal Server thread terminating
3/1 21:42:58 srvc !ERROR loading configuration files: 2 opening /opt/sbbs/ctrl/text.dat
[Threads: 5  Sockets: 0  Clients: 0  Served: 0  Errors: 2] (?=Help): Segmentation fault (core dumped)
```

When I initialised the configuration (which puts in place ctrl it stays running :)
