Shutdown/crash logging

[Kattihatt]

So sometimes when I use Google assistant it breaks of mid response or doesn't respond at all. After that it becomes completely unresponsive and the RPi becomes unreachable and shuts down. I don't know if the shutdown issue is directly connected to the use of Google assistant but it's the only connection I can see. I would like to see what causes this but I can't find the log files or any other indication of what could be wrong. I know how to use journalctl -f for looking for issues but this hardly helps when the system shuts down and I need to see the logfiles. How would I go about this to find the issues?

You could check /var/log/daemon.log the journalctl logs should also be in there. Older logs when the file gets to big are gun zipped for example /var/log/daemon.log.1.gz

If the RPi is shutting down, it probably means that your power supply isn't supplying enough current. What kind of power supply do you have? We recommend a 2.5A power supply.

@drigz Feeding it through a LM2596 fed directly to the GPIO-pins, so I've never had any problems with supplying power. The buck converter can do 3 A continuously and above for short periods. It dies in connection to me using Google assistant and this last day, I've had to restart the service three times after it becoming unresponsive. The RPi didn't shut down though.

@divx118 Thank you! Red lines about every tenth row complaining to being unable to connect to Google and a lot of other errors, all connected to Google assistant. Now I got something to work with at least.

Could be the same as #188.

@drigz No, but I've experienced that as well. After losing connection I have to manually restart the service for it to work.

OK, thanks for the clarifications. By the way, if you wrap multiline code snippets with three backticks, it renders properly. eg:

```
line one
line two
```

@Kattihatt Not sure if you are still working on this project but is this also reproducible with latest AIY image https://github.com/google/aiyprojects-raspbian/releases/tag/v20191113 ?
