Description
I have a VirtualBox machine running debian and nginx. I have set up a shared folder between my local machine (Ubuntu 12.04) and the vb machine and I am serving static files from this shared folder.
When I open one of the files in my web browser nginx serves the file correctly, but if I then make a change to it from my local machine, nginx serves the old version, but adds some weird characters. If I open the file on my vb machine with vim (or any other text editor) the file is correctly updated and if I save it (without changing anything else) nginx starts serving the file correctly again.
Some more info is available on my blog: http://smotko.si/nginx-static-file-problem/.

The comment on reddit is probably correct -- it looks like a bug in VirtualBox vfs/sendfile implementation.

This is an old well-known bug with the mmap/sendfile implementation in vboxvfs:

Thanks to a comment on reddit I found a solution to this problem.
