* Added another troubleshooting step

After a chat with petergebruers, these error messages are good ways of identify if you've made the mistake of running multiple things that access the controller, which breaks your system in strange and mysterious ways.

* Minor changes

@ -263,3 +263,15 @@ If you're getting errors like:
openzwave-embed/open-zwave-master/libopenzwave.a: No such file or directory
Then the problem is that you're missing `libudev-dev` (or the equivalent for your distribution), please [install it](/docs/z-wave/installation/#linux-except-hassbian).
### {% linkable_title Random failures %}
If you're having random failures of the mesh, devices going missing, things randomly not working, check your `OZW_Log.txt` for the following messages:
```
WARNING: 500ms passed without reading the rest of the frame...aborting frame read
WARNING: Out of frame flow! (0xfe). Sending NAK
WARNING: Checksum incorrect - sending NAK
```
If you see any of these messages repeated in the log then _probably_ you've got something else running that's also using the Z-Wave controller. That might mean you've also got the OpenZ-Wave control panel (ozwcp) running, a second instance of Home Assistant or something else. You need to stop that other process to resolve this.
