Out of memory on r-pi 3 #10

Closed hamishfagg closed 6 years ago

hamishfagg commented 6 years ago

Python version 3.5.3 Kernel version Linux raspberrypi 4.9.59+

In kern.log about the kill:

I haven't noticed this in mine. I currently have it running for over a few months without issues.

I'm on a fully updated raspbian.
