I have a directory /home/user/MyDocs/.sounds/Music that contains all my music (encoded in AAC+).
I have organized my music in a folder structure artist/album/ and (according to mp3tag) all my tags are correct.
When I build the tracker database (using trackercfg) I only see around 40% of my songs, there are just over 5000 tracks and media player tells me there are just over 2000.
If I look at the trackerd log, there are loads and loads of entries that say:

Tracker-Critical **: Could not open directory 'file:///home/user/MyDocs/.sounds/Music/artist/album': Too many open files

Where artist and album are part of my collection. What does this actually mean and how do I get round it so that media player sees all my tracks?
