@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. :-)

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

Now i will check it out with jessie :-(

@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?

@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.

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

This is my sylog

Nov 9 22:03:06 raspi32 kernel: [ 5458.473560] Out of memory: Kill process 880 (electron) score 948 or sacrifice child
Nov 9 22:03:06 raspi32 kernel: [ 5458.473695] Killed process 880 (electron) total-vm:981380kB, anon-rss:671832kB, file-rss:104kB, shmem-rss:7180kB
Nov 9 22:05:58 raspi32 systemd[1]: Started Session c4 of user pi.

This is not realy what i can use. I dont like to change to debian 8.

Is anyone able to show me a list of used modules, memory and uptime ?

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.git

my 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?
