in my case it was a python app (flask restful) that when run in debug mode
would restart if some file changed,
but some days ago that stopped working, Since I had updated the kernel and the
ports it took me some time
to find out what had happened, it had nothing to do with the upgrades but
instead I had installed ‘watchdog.py’ which
flaks->werkseig->reload decided to use :-(
rabbit hole indeed.
