Meteor keeps getting stuck after save


In a big Meteor application I am working on I have the problem that Meteor gets stuck when I save a change. It happens every couple of saves, sometimes it works, the next time it refuses. After a save the client nor server refreshes. The app refuses to load in the browser. When I press ctrl + C in the terminal to stop and restart Meteor it takes around 20/30 second before the Meteor process is stopped (stuck in infinity loop?). After a restart the code works just fine.

Any clues on how to trace back this error. I do see anything special in Kadira. No error messages in either console.

Thanks for your thoughts.

I managed to track it down that the node process is running at 100% - any suggestions?
