With appledouble = v2 in afp.conf there is an fd leak in certain circumstances while using the Finder. This can lead to an afpd process using 11000+ file descriptors given enough time.
Server: FreeBSD 9.2 (netatalk 3.1.0)
Client: Mac OS X 10.9.2
How to reproduce:
Attached is a debug log where I click around in a folder with images and the process leaks around 300 fd.
