I writting a file under the appliction directory, like 'cache/filecache.json',
and start the application with command 'fastify start --log-level info --pretty-logs app.js'.
If the file was changed, an error will show in terminal, "[fastify-cli] process forced end"

of course, this error can be avoided by '--ignore-watch'.
But when I use nodemon, there's no such error, so I submit this
