What file system are you using?  Could it be something in the zfs 
indexing.  Since a standard ls works, and smaller directories work for 
sorted output, this sounds more like journaling or indexing.  I'm not an 
SA, so there may be more technical ways to say this, but have them look 
at your file system settings and the indexing and journaling parameters 
on the server.
