Black Screen Of Death After Couple of Hours

dazza120

Hi, as per the description, my magic mirror seems to go black screen after about 6 or so hours the first time i done the magic mirror on the Pi 3B+ the SD corrupted its a Sand disk 32Gb extreme, Pi is connected via ethernet and connection via VNC server. Im a Noob so be gentle :) ive looked every where for a solution other than starting a cronjob every 6 hours which is a pain as ive installed MMM-voice and want to control it through that but cronjob pm2 restart mm, loads everything afresh again meaning you have to change it to voice mode and all modules are displayed.

List of Modules MMM-NetworkConnection, default cal to UK, clock,weather forecast, current weather all default ones, updatenotification has been deleted from config.js. MMM-GoogleMapsTraffic, MMM-Hue and MMM-SystemStatus. So the magic mirror screen has gone black and its still open just alt-m and im connected via VNC and typing this on my iphone via the Pi so im actually doing this through the pi with 5chromium pages open and terminal so the pi itself hasn’t crashed. Ill post a log to the crash hopefully someone can help me out but seems that the black screen of death is not a new thing but still cant find a solution to it. thanks in advance for your help.

means no memory available to lauch the background app…

usually means doing more than physical memory can handle…

so… see https://www.answiz.com/questions/22232/node-js-catch-enomem-error-thrown-after-spawn
to verify no swap and enable it

mmm-voice…
YOU don’t have to change to voice mode… just speak and IT will change the first time… (least thats what happens for me)

Thanks that’s a bummer :( i’ll Try changing the update intervals for GoogleMapsTraffic as that’s what it could be, thanks for your help

@fonfon which module are you using? AFAIK @sdetweil created a modified version to stop the memory issue. At least that’s what I vaguely remember.

I am sure he’ll pass by within minutes to either confirm or deny :beaming_face_with_smiling_eyes:

Fonfon

@sdetweil , ok thanks @MadScientist i find the modified module
how i can change mine only on change this file “MMM-GoogleMapsTraffic.js”

Thanks !

MadScientist

@fonfon The way I would do it:
Rename the old folder of the old Maps-Module and download the new, modified version. Enter the folder of the new version and run npm install. Config should be the same, so no need to change anything there.

Test and report back if everything worked.
