MagicMirrorOS build intermittently not starting mm container (Version 2.30)

@sdetweil

well, I did not promote it because the image base was to old (beside other problems) but in 2024 I decided to do a complete refactor so now the image build (iso, not docker) is done by me with gitlab based on the current raspian bookworm os lite.

@scottwalsh please dont double post

@sdetweil
The host is a pi zero 2w - so is on the low spec side.

Apologies, user error.

@scottwalsh how big is the swap file?

free -m

will tell you

@karsten13 @scottwalsh
bookworm is about 500m bigger that bullseye

so swap is critical on small memory machines

[karsten13]

mmos is critical with pi zero 2w, I had a user who gave up, but it depends on installed modules and quality of used sd-card.

CONF_SWAPSIZE=1024 (if not changed by user)

@scottwalsh can you show w MagicMirror running…

[scottwalsh]

An observation, if I power cycle the pi, there is a good chance of it not starting up with the errors in the original post.

Once leave it for five min for all the processes to start (and fail), then run docker compose up -d --force-recreate, it seems to be stable from then on and works well.
