For those following, @ebradbury and I have resolved this issue by replacing the source image of
FROM balenalib/raspberrypi3-alpine-python:3.8-latest
and instead moved to
FROM balenalib/fincm3-python:3-stretch-run.
This has resolved all of our issues with livepush and laggy local performance. Not clear why. Mentioning here as a cross reference to our alternate but related conversation on https://forums.balena.io/t/is-there-a-maximum-number-allowable-containers/146698/33
I’m not sure this is an Alpine specific issue but may be more a bug related to Alpine with livepush. Completely conjecture but wanted to bring to the Balena / Fin Team’s attention.
