I'm sorry this is late as I don't have FreeBSD installed any more on my server. Posting this nevertheless so that FreeBSD maintainers is aware of the problem.

Copy/paste from the rtorrent bugtracker (http://libtorrent.rakshasa.no/ticket/2470):

"I've got a folder structure that leads to files being 5 folder levels below / (like so: /data/files/in/this/folder). I've got my downloads in another directory 3 levels below /. Symlinking files (or folders) to my torrent download directory makes rtorrent error with "Hashing: Storage error: [Hash checker was unable to map chunk: Too many levels". The file names are generally quite long, but do not exceed the 255-character limit."

This was on a 3 disk ZRAID.

This problem is not reproducable in Linux with approximately the same folder structure.
>How-To-Repeat:
ln -s /data/files/in/this/folder /downloads/goes/here
start rtorrent with it's download folder directed at the /downloads/goes/here folder with folders symlinked to it from /data/files/in/this/folder
>Fix:
None.
