home-assistant.io crashes my SBC after a while (race condition?)

[Ashok Aiyar]

Hello,

I installed home-assistant.io on my Odroid XU4 two weeks ago. It was easy to configure it work with my Wink account and ecobee thermostat.  And when it works, its great.

This Odroid has an octacore processor (Samsung Exynos 5422), and 2 GB memory. It is running Ubuntu 14.04, Linux kernel 3.10.92. The Python version is 3.4. I am running home-assistant.io in daemon mode (hass --daemon)

However, within a day, the computer slows to a crawl and then crashes, requiring a hard reboot. The only thing that I've noticed is that the hass process consumes a lot of CPU (17% to >80%) before the computer slows down and then crashes. I've attached an image file showing the output of top.

What should I do to fix this?

This is what the contents of home-assistant.log shows when it starts up. BTW, although there are ecobee errors, the thermostat shows up fine in the home-assistant.io web GUI.

Any other errors logged in your home-assistant.log file? You can find it in your config directory.

It must be one of your components or platforms that is causing this. Can you post a list of the components and platforms that you use?

It's nice to be important but it's more important to be nice.
