Harris, 
this bug got fixed a while back. Are you still facing the same issue? 

thanks,

I am testing 2.5-patch-194. I have a two brick setup with ns setup as a second volume on the second brick. 

I am exporting /mnt/export on the bricks and /mnt/namespace on the ns volume 

All seems ok but the namespace cache is not filling completely. 

[root at domU- 12-31-35 - 00-36-41 :~] find /mnt/export/ -type d -ls | wc -l 
3947 
[root at domU- 12-31-35 - 00-36-41 :~] find /mnt/namespace/ -type d -ls | wc -l 
103 

This is causing read failures on the clients
