Maybe this can be the cause?

@cruunnerr
I’m working 🙄 didn’t test anything yet 😅

@retroflex I also got the same issue. MMM-resrobot or something it depends on looks to be causing this. Has anyone found a workaround? Resrobot is one of the main reasons I have the mirror so not really happy about disableing it.

@Alvinger Do you know what could be the problem with ResRobot here?

Alvinger

@retroflex I can’t think of anythong off hand.

I am running an older version of MM myself so haven’t researched the electron issues.
Can anyone confirm that the issue started with the new MM version?

As I am running my magic mirror on an original Pi 1 with 256MB RAM with no issues whatsoever I am a bit surprised that the module should cause this.

Edit: MMM-ResRobot has but one dependency and that is the unirest module.

Which version of ResRobot are you running? I did a rewrite to reduce the number of updates w while ago.

@alvinger In my case, the problem started after last MM update.

Same here. Running the latest ResRobot.

But I think others have reported the same problem but with a different module.

@binog @FredJ @cyberdie @schlachtkreuzer6

Looking through the unirest dependencies it looks like it relies on express which may or may not make it sus eptible to the issues with electron.

To resolve this I replaced unirest with node-fetch and pushed the new version of MMM-ResRobot to github.

To upgrade cd to your MagicMirror directory and run the following commands:

git pull
npm remove unirest
npm install

Please post results in this thread!
Hope this resolves the issue.

@Alvinger Thanks for the quick fix! :)

My first test…

“top” without ResRobot shows about 1% CPU when idle.
Added ResRobot (old version): “top” shows 100% CPU all the time.
Updated ResRobot, removed unirest, npm install: “top” now shows 1% CPU when idle. Yay!

Looks good so far. Too early to tell anything about memory leaks, but I will keep my mirror running and check tonight. Currently electron shows 18% mem used (for the 2 electron processes).
