adding the line below to MagicMirror/js/electron.js has helped for me

function createWindow() {
	app.commandLine.appendSwitch("autoplay-policy", "no-user-gesture-required");
	app.commandLine.appendSwitch('disable-http-cache');  // < ---- add this line
	var electronOptionsDefaults = {

@sdetweil thanks for reaching out!
I’ve made the change you proposed but MM hangs again :-(
What i can see from MagicMirror-error.log is this:

look at

free -m

u may need to increase swap space u have a bunch of stuff running
https://wpitchoune.net/tricks/raspberry_pi3_increase_swap_size.html

also, open the developers window, ctrl-shift-i on the keyboard, select the tab labeled ‘console’ and scroll up, looking for any errors (usually red text)… or any other errors reported

the terminal window messages are from the module node_helpers
the dev window are from the modules main file (we call it the modulename.js as its name matches the module name)

no single place collects it all

@sdetweil I have lot of free memory, no swap at all what i can see :-)
But i found theese errors in the console (maybe hard to tell why…):

do you have a custom compliments configuration?

this is part of a fix I put in for compliments with embedded ‘\n’ newline characters

but the code said that it came up with no compliment to use from the list of morning/afternoon/evening/anytime configured compliments

if u want to turn that module off, then add
disabled: true,

to its config entry (after module: ‘compliments’,)

hedmik

@sdetweil Hi again, and i’m very grateful for you helping me out :-)
Yes, i have both the standard and also a custom compliments module and by turning that custome module off MM is still running since one hour!!!
I’m so happy back on track again (cross my fingers) :-)
I will now focus on enhancing MMM-Telldus and MMM-Vastrafik modules.
I’ve also seen nice enhancements made for Weather forcast module (more descriptive text and translated to Swedish). Hope to get those enhancements otherwise i’ll do it mysfelf.
I’m also planning to develop a module for Engage (showing electricity consumption within the household).
Once again, big thanks!

fantastic…!!

it might be a mispelling or something but it can’t find ANY actual compliment text…

@sdetweil
What exactly do you mean by a “custom compliments module”? I am using the default “compliments” module but with “remoteFile” for the quotes. Is that what you are referring to as “custom”?

Since upgrading from a Pi Zero W running Stretch, I have been having the same issues as both of you (RP3B+/Buster/Latest MM/and then did the Electron upgrade to electron@6.0.12 as mentioned in the updated installation documentation).

When running MMM-BackgroundSlideshow on Zero before I would occasionally get race events, so I recently moved to RP3 with a fresh install, and I turned on “transitions” between photos as I thought the beefier CPU would handle it. But it would hang after a while and I’ve been trying to diagnose ever sense. I’ve set “transitions” back to false and the Pi still hangs. I’ve increased swap. I’ve increased GPU mem. Tracked with nmon, and except for the occasional CPU wait% going up every once in a while, I was never low on memory or disk.

I just happened to run across this thread and it seems almost exactly the same issues.

I’m slowly adding back in all the modules and will now put back in MMM-BackgroundSlideshow before adding compliments. I really never thought one of the default modules would be the issue. I actually thought it was some incompatibility between Buster and Electron.

I’ll report my findings.

by a “custom compliments module”

I said custom compliments configuration, not module

so, yes, u are, as u are supplying the compliment strings in a file…

can we see that file… is it the in the compliments module folder? (it must be)
and for linux systems the filename case matters, and must match EXACTLY whatever u specify int her remoteFile: config option

custom compliments module

do you mean configuration? is this remoteFile: in the config?

is that file in the compliments modules folder? it must be.
