Port 35729 is already in use by another process

I’ve run into this error a couple of times recently when using the Yeoman webapp generator with Livereload. After trying changing the port used by the Livereload server in the Gruntfile and still seeing the error, running this command in the terminal…

lsof | grep 35729

…confirmed that Sublime Text was the port hogging culprit. Specifically the Livereload Sublime plugin. Disabling this plugin resolved the conflict.
