Repro steps

Our team do have strange issue. Angular CLI keeps recompiling constantly.
We are running project with ng serve --host=localhost.domain.com --port=8081 --configuration=dev --verbose

And after sometime it will recompile even we dont change anything

But if I run same command without --verbose then output will be:

  • Some times is so bad that it recompile almost once a minute.
  • From observation it starts as soon as I do first change and save.
  • Company has strict security so I am not sure which software is installed.
  • For some team member is ok they dont have this problem.
  • Same problem is with karma tests they keep recompiling
