I don't have any hands on experience with such a large database. I tried
gnupod_add and _search with about 24000 files but only as a dry run into a 
directory. I use a Nano 3G (8GB) so I can't actually try anything close 
to your collection's size on the device.

If it was a 2^15 problem it would have struck at 32768, so going below 32946
you would still have almost 200 files too many. Could you post the complete
output of mktunes?

You don't need to subscribe if I put you on Cc: . But if you like to, you can 
subscribe at http://lists.nongnu.org/mailman/listinfo/bug-gnupod
The list is very low volume.

This could indeed be a problem for the iPod software. I don't know the
binary format of the iTunesDB but messing with references like that could 
cause problems for the database parser on the ipod.

I suggest you try to add those files without adding cross references first.

BTW: Which version of gnupod are you using?
