I think this is a limit on the Linux VFS structures. I don't know how to tune 
it, or if it is tunable upwards in a simple fashion.

The problem is when you have more than 31998 in an ext2 file system.

Since there are underlying structures with similar limits, it will likely 
affect many file systems,  although you may get closed to 32768 before it 
fails.

Probably best to use a hierarchical naming strategy to avoid so many 
directories at the same level in the 
tree; /var/spool/mail/domain/us/er/username

Hans Reiser has commented the underlying limits make his file system look bad, 
although he didn't put it that brutally.
