I have a large collection of files (roughly 200 000) and the default settings for MPD will not allow you to do something like:
-------------------------------------------------------------------
[root@runeaudio ~]# mpc listall | wc -l
error: Connection closed by the server
-------------------------------------------------------------------
I changed the 'max_output_buffer_size' setting in mpd.conf and things are now working properly, could we have a tweak button for very large collections?
