which points to a graphical module, globe, something doing heavy charts.

@sdetweil
you are correct electron is hoarding resources.
Is there a way to kill a PID in debian to see what module may be causing this.
1998
1988
and 1949 are top three cpu hogs…

sdetweil

@plainbroke you can

sudo kill -9 pid

but i dont know what functions are in what process, electron decides that. one is the page/tab

@sdetweil
Just did a kill 1998 and it is now not showing up but the mirror is still working,
I guess I will wait until one of the modules doesn’t work anymore.
Then i will know which one to remove, right?
Turns out that was the wireless connection I think.
MM stopped and I can not access it through ssh time to POPO.
I will keep after this but I will also stop globe in the config.js. just to see if that helps.
Thanks for your help I have learned alot tonight about the way debian and MM run.

@plainbroke i think page switching while globe is drawing
is probably the cause

@plainbroke this is the best Answer

Not so sure that it was globe came home today and the same screen was stopped,
MMM-Dogs and the time was the same 3:37 pm but the real time was 4:30 pm.
So re-enabled globe and disabled MMM-Dogs to see if it does it again tomorrow…
I am almost wondering if it isn’t something to do with MMM-birthday-paged.
It was the last module I remember adding since this started.
I will slowly figure it out by disabling one module at a time that seems to hog resources.

By the way what do it mean by zombie in top.?

@plainbroke i think most often is the parent dies but the child was still running…

Found It

ps ux | awk '{if($8=="Z") print}'
pi          1170  0.0  0.0      0     0 ?        Z    16:36   0:00 [xsettingsd] <defunct>

What is xsettingsd?
Should x11 be running with wayland ?
Seems like a duplicated background app running or do they not do basically the same thing.?

I did kill the 1166 which turned out to be the parent of the 1170 xsettingsd
Mirror restarted I assume due to PM2 being involved.
It restarted MUCH faster than normal. The MMM-Snow is running smoother.
I guess only time will tell.
