Spring app eating cpu in background

[dmitryn]

Hi!

Recently i noticed some strange activity happening through top. It turned out that after specs have been runned, spring app process is still active and using ~%20 cpu while nothing happens (no tests/tasks running). I have to stop the process via spring stop.

I'm using ubuntu with virtualbox.

Any tips on how to debug it?

It may be the default method of watching for changed files, which scans the directory tree instead of using whatever change notification mechanism is provided by your operating system. See https://github.com/rails/spring#watching-files-and-directories.

@sjmadsen thanks for explanation! Switching to listen method.
