4 electron processes with 2 GB ram after 2 days?

[W-M-B]

Hi,
I have looked aroudn to see how many electron.js processes MM2 will start and how much memory consume - no success.

I have MM2 running since June 2019 with
pm2
Core Modules (with google calender, weather, news, analog watch)
MMM-pages
MMM-page-indicator
MMM-Spotify
MMM-WienerLinien (local Transport in Vienna).
After 2 days of running the consumption is approx 2 GB. (see pic1)
After reboot it looks like this (pic2).
main screen is a 7" touch display!

running 2 days
restarted
Is this normal behaviour or is something wrong?
