Hi everybody,
I think I have a memory issue and I am looking for some advice to solve that.
I am running newest Mirror and only a few modules on a Pi 3B+.
The system works fine, actually mainly displaying calendar, time, weather and pictures (MMM-BackgroundSlideshow).
I am running in overlay file system.
Sometimes (I think when RAM is full - but that is just a guess for now), the screen is frozen.
If it was displaying, then the last display is frozen. When is was disabled by PIR, then it comes up black and all I can see is the mouse pointer from the desktop.
In that conditions, I still can view the “normal” mirror screen when opening the IP address on a different PC - works normally.
I also can access the PI via ssh (most of the times).
Also sometimes I can still restart the mirror with Remote module.
The memory is filled up (I guess mainly due to the pictures shown) and to my feeling the “freeze” happens when RAM is full. But for some reason it then gets freed-up and filles again - just not displaying on screen anymore, like this:
(during the first two free-requests is was still working normally, then if froze and the last free-request is in frozen state - server still running showing normal screen on webbrowser of PC)
Am I correct in suspecting RAM resources to be the problem?
Is there any way to clear something (cron jon, scheduler request, etc.) during runtime?
Or would I need to stop the mirror and restart it to free RAM?
Any hint appreciated.
