Error: Unable to create file group; too many existing file groups. <-- why?   
Client of MME trying to retrieve metadata from a mediafs_2wire filesystem via the explorer API:

   x_info = mme_explore_info_get( x_hdl, get_flags );
   display_name = mme_metadata_extract_string(x_info->metadata, METADATA_TITLE, 0);

This succeeds in most of the cases but sometimes mme_metadata_extract_string() would return NULL and MME emit the 
following log (verbatim log extract below):
   Unable to create file group; too many existing file groups.
   Unable to get metadata

What kind of user error may lead to this error?
Can it be caused by an error in the mediafs driver?

The issue has never been observed with an iPod but happens from time to time with the custom mediafs driver.

I think this is an MME bug.

This is not a bug. This is a design limitation in the MME.

Basically, for that metadata session there are too many combinations of metadata groups being requested. There is 
currently a hard coded limit of 32.

To hit this limit, it would be interesting to see what is happening, and why metadata is being requested for so many 
different sets of metadata types.

What is the mediastore that they're seeing this on and what sort of content
is on it (media related and non-media...)

I saw this a while back in PR 64866 but I had a number of test media directories
in place that caused the limits to be hit.
