What tags does the file have? What tags does MPD show for this file? What does this have to do with NFS and httpd? Do tags work with any other storage/input/output plugin?
Tags are ok - its just the ICY metadata. Applies to all (at least MP3) files located on my nfs v4 server. Why nfs? my local hdd is full and my nfs server has plenty of free space. Why httpd? I use Sonos (Symfonisk) as some kind of kitchen radio. ICY metadata is ok wenn using http input plugin (eg byte fm) and playing to httpd output.

I can't reproduce this problem. I get Icy no matter if the file was played from local disk or from NFS.
Sigh. Unfortunately, the problem still persists for me. I'll try to narrow down my system's strange behavior over the next few weeks.
Thanks for your effort, Max.
