I had to reboot the machine I have Discourse running on to replace a bad graphics card. However, Discourse won’t restart. When I try `./launcher restart app` from within `/var/discourse`, I see:
```plaintext
clay@machine:/var/discourse$ ./launcher restart app
+ /usr/bin/docker stop -t 10 app
app
starting up existing container
+ /usr/bin/docker start app
Error response from daemon: Cannot start container app: Bind for 0.0.0.0:9999 failed: port is already allocated
Error: failed to start containers: [app]
```
When I `docker ps -a` it looks like:
```plaintext
clay@machine:/var/discourse$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1784278bfaa7 local_discourse/app "/sbin/boot" 4 weeks ago Exited (143) 18 minutes ago app

```
That sort of makes it look like an old version of Discourse is running?
What’s going on here? How can I get Discourse up and running again? All was fine before I shut down and rebooted.

Ok - I just stopped the “old” discourse and started the proper one with `./launcher start app`. What was that ‘old’ discourse and how do I make sure that doesn’t happen again?

Well… it probably won’t. Any real clues we might have had as to why are probably gone by now. If it happens again, that’s when we need to worry.
