@joern this sounds like a corrupt SD card.

the memory technology is write once. when writing again the prior bits are marked as used.
problem, the file system does not know, and there is no signal of full…

so then it ‘thinks’ it wrote out data but it didn’t.
the only fix is a new card. maybe you can read some older stuff off.

@Joern if the module supplies a package.json, then you should do npm install in the module folder

bottom 110% was first try, but cutted away parts on left side :-( even if there was space… Margin 0, if not other issues will come - works fine as mirror is anyhow bigger…

Thanks, Iam not very familiar with Docker compilation, then I will try a fresh install in old school way and rotate screen by CSS, that also saved a lot of CPU/GPU use already…

@ant62130 I have added a check for user being root… thanks again for the report and feedback

I was struggling with a crash. I logged the mem usage with SAR

sudo apt-get install sysstat

Then I output to a log every few minutes so if it did crash I could go back through.

sar -r 1 > somefile.log

The exact issue I was having was with an iFrame Module iFrame-Ping:

MMM-iFramePing

I run a YouTube Playlist - that will eventually bring up the module by voice command.

//iFrame Module - Contains Fox News Playlist on YouTube - Autoplay - Modest Branding (no logo) - iv Load Policy = 3 (no annotations) - Controls = 0 (no controls shown) { module: 'MMM-iFrame-Ping', position: 'top_right', config: { url: "https://www.youtube.com/embed/?listType=playlist&list=PLlTLHnxSVuIyeEZPBIQF_krewJkY2JSwi&index=-1&autoplay=1&modestbranding=1&iv_load_policy=3&controls=0", autoRefresh: true, updateInterval: 120, width: "560px", height: "340px", scrolling: "no" } },

The iFrame video was crashing the PI so I decided to increase the swapfile size. Before I increased the size my PI would make it about 2-4 hours. Now I can literally run it for days without an issue.

sudo nano /etc/dphys-swapfile

Change CONF_SWAPSIZE=100

CONF_SWAPSIZE=1024

Stop/Start the Service

sudo /etc/init.d/dphys-swapfile stop sudo /etc/init.d/dphys-swapfile start

You can log with SAR or just do

free -m

Some people set the swapfile to 0, but others warn against it. If you want to

CONF_SWAPSIZE=0

Yeah i know that benchmark (using that speech recognition with my mirror already) :) (newer reapeakers not included there yet they definetly perform a lot better with background music as they use the xvf3000 resulting in them nearly completely removing the background music from any samples)
When I saw it it was used in a small robot with speech recognition and it absolutely failed with a distance over around 1 m, but it was on a hackathon so maybe it was just the background noise causing problems.
@dvbit it just sends all four channels to the pc aswell? or does it already create just one channel out of the four?
