Out of memory error

Every now and then the application crashes with the following error message :

It looks like there might be some kind of memory leak?

I am using the app to serve a local file containing my todo's, which I edit regularly. I am really enjoying how the app reloads the file as I change it. However it seems like if the server has been running for a while and/or I make several edits while it is running, it eventually crashes with the above error.

I use the app for a similar purpose and got the same error just now -- I'll capture it more carefully next time and see if I can provide more info.
