This is tested with a client that is querying the SUD once every 30 mins. When it fails I'm seeing the error shown before.

Platform Hass.io 0.87.0 on Raspberry Pi

Moved system to HASS OS with HA 0.93 and it's even more unstable now. It is only managing to get an hour or two of reads before falling over now. Still investigating.

I've tried simulating this on a Raspbian system and have had uptimes of a couple of weeks, with no issues. I suspect this is related to the Hass.io and HASS OS images/OSes.

I have seen this on a Raspbian system as well, I had the program running for around a week without problem, and then it stops talking to the seneye. I have not yet figured out why, but I restart the raspberry pi manually when this happens. I will try to investigate next time it happens.
