There have been some "optimizations" for NFS in earlier kernel, leading 
to large space reservation per open file. Marc Lehman yelled at that 
early August in thread "frequent kernel BUG and lockups - 2.6.39 + 
xfs_fsr". Maybe that's your problem too? Do you use "allocsize=" mount 
option? It could be your new kernel version fixed that, but I can't 
tell, as I'm not a dev.

inode64 helps in case there is no more space in the area <1TB. As you 
have "only" 4TB, chances are it wouldn't make a difference for you. 
Somebody once posted a [perl?] script on this list to find out how much 
space is left at <1TB, maybe that can be of help.
