UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 0-1: unexpected end of data

Chiadog was working fine for days, then it started reporting that my harvester was offline, but that was not the case. This is what I found in the chiadog logs:

...

I restarted chiadog's container and it started functioning properly again.

Seems related to #327 we should catch that exception, log it, and retry without killing the thread.
