Service #39

Open MartinKei opened 2 years ago

MartinKei commented 2 years ago

Issue Description

Service stopped working but not running when facing Kraken API issues. Process is still "running" but doesn't do anything. (eg. executing triggers, sending Telegram notifs, etc.) Due to the process still running, systemd isn't able to restart it.

Expectation

As said above, I'd be happy with either of:

System

Raspberry Pi 3 B with Raspbian Using systemd

I don't really see what we could do about that. The program catches this exception and ignores it. And they keep on coming?

MartinKei commented 2 years ago

@martin-ueding the issue isn't about the exception keep on coming, but that the application stopped checking triggers.

It just kept running without doing anything.

No "I am still here!" messages, no triggers execution, nothing.

My expectation is that the app either exits with an error, or continue on with it's inner lifecycle.

martin-ueding commented 2 years ago

Yes, that indeed sounds like a very strange bug. If that happens again, could you perhaps use sudo py-spy dump --pid PID with the process ID of the program to see where it is stuck?
