MM is eating all memory and crash!
-
Now after two weeks, two different SD Cards and two totaly separated new installations i am at the end of my brain.
Raspberry 2 B+ with latest stretch
First i had to downgrade electron to 1.4.15 couse of high cpu usage (over 300%) and stocking seconds on screen in clock module. Like 21…25…35… till nothing anymore.
Now i am checking my ram usage. With maybee 6 modules like
clock
weather
weatherforecast
MMM-cryptocurrency.git
MMM-swisstransport.git
MMM-pihole-stats.gitmy MM is running only 2 or 3 hours. After that my memory is less than 13% or apr. 100MB free i got the same problem as above.
Now i check same problem with only 3 standard module. Since last 12h my memory decreased from 50% free to 28% now and counting down.
What the hell can i do?
-
Is anyone able to show me a list of used modules, memory and uptime ?

About three months ago most all of these concerns were addressed by me and a few other fantastic people. We did quite a bit of troubleshooting. You will certainly benefit from reading through this and taking the necessary steps:
https://forum.magicmirror.builders/topic/4684/electron-cpu-usageNote:
Most, if not all of the people involved, were using a Pi3.
Some modules present a higher system load than others.Opinion:
Use Jessie, not Stretch

Now i changed to Raspberry 3. After 2h system crashed. 4MB memory left.
This is my sylog

A memory leak was discussed in the topic I recommended to you. Was that result with the default installation of MM or did you add other modules?
This is not realy what i can use. I dont like to change to debian 8.
Your choice, sir. Good luck :-)
-
@Mykle1 With Rasp 3 i checked again with this six modules on 1. thread. Whitch Raspi .iso do you guy use for MM? Maybee i should install all things manual instead of this automatic installation? Memory leak not possible couse of Raspi 2 was the same issue and 2 different SD Cards.

-
@Mykle1 Yes i read it. All of this suggestions i already checked out. If you tell me to test standard installation whitout any additional modules - what the hell do all this people building such modules when i only can use standard modules?
Dont misunderstand me. But i manage two root servers with kvm - lvm and aprox. 30 official domains and nearly 200 email accounts. Longest uptime was 772 days. Nobody can tell me a application with black background and some “only text foreground apps” should not be able to run more than 2 hours or not?

Very good. You had the benefit of other people’s time and hard work. Imagine if you had to think of all those tests for yourself.
If you tell me to test standard installation whitout any additional modules - what the hell do all this people building such modules when i only can use standard modules?
Logically, that would be a starting point, to see if the issue arises before the addition of other modules. If the problem arises afterward, then you can attribute the cause to something that you added. If not, then the cause lies in the OS version, the MM version, or with the Pi itself, or the way it was prepared.

I could not be less impressed.

Nobody is telling you anything. I thought you wanted help so I started where anyone would start, at the beginning. Instead of some small measure of gratitude, you started spewing your impotent anger at me.
I only have one more question for you.
With the impressive resume you have, why didn’t you just figure it out and fix it yourself? :-)

You are in the minority … I have 3 running, without issues… 1 of them has been running a solid year without any issues what-so-ever.
With that being said being rude to someone trying to help you is not really a way to get help…

Oh, and MM specifically is up for 20days:

Uninstall PiHole. If you search this forum for PiHole you will find two other threads with similar memory issues, both related to PiHole. After removing it the issue was gone.

@all Ok sorry. Now my realy newest installation on Raspi 3 stretch wiht realy original config.js and no additional modules or other changes:

This post is deleted! -
@yawns Thanks. But last “overnight” test with only original config.js also crashed with stretch. So now a new test with jessie looks much better. Including pi-hole. It runs since 22 mins and 47% free ram. :-)

@juergschwarz
Thanks for your feedback, good to know. So one more reason against Stretch -
