@martinkooij TBH, I have no clue how to check my electron version, but I used the MM install script and haven’t downgraded anything. So I’m running the version supplied by the script as of approximately two weeks ago.
I’ve not noticed any mem issues. My mirror’s been up 6 days mem usage is ~10% per process:

Could it be a module causing it? Or try reinstalling MM with the script and see what happens with the default install/modules
As far as my modules go, I’m only using the date and weather mods from standard and then 4 custom mods(technically 2, as 3 are separate instances of the same mod for bus/train times).
