CPU hogging to 100%

Hello all !
brand new subscriber, I was looking for a way to debug my cpu-hog-matter, I found this (pretty old ^_^°) thread and wanted to share a thing : my cpu hog was caused by my Range Finder node (not actually mine : node-red-node-pi), but it appeared that I used a python script which was visible through 'sudo htop'... May it help someone...
