mt-daapd crashes “Address already in use”

Greetings,

I’m running mt-daapd on an NLSU2. Yesterday I tried running it with only about 15 mp3 files in the directory, and it seemed to work fine.
Now, when I have copied all my 4,000 some files to the directory, mt-daapd crashes during the mp3 file scan:

2005-04-04 22:40:49: Rendezvous socket closed (daap server crashed?) Aborting.

What could be causing this?
