Widget freezing whole bar. Could you help?

[dandudzi]

Hello,
based on the shared here bar examples I have created my own setup.
However one of the widgets causing SketchyBar freezing and not responding. It is happening after some time ~30 min running without any issues. Hence I need to run brew services restart sketchybar to make it work again.
I am sharing my setup here, currently widget total_memory.lua is disabled because causing troubles.

Could you help me with understanding what could go wrong with my implementation of total_memory.lua?
Do you see any obvious bugs in my lua settings?
I was trying to print some logs to console but I do not know where the logger is pointing? Could you help?
Any tips how to debbug the issue or what tool use to monitor this lua program?
