 Are you using v3 NFS or v2?  Switching to v2 has made things MUCH more
 stable for me, however, I still loose stability with ZIL enabled (even if
 prefetch is disabled)(and ZIL disabled is NOT desirable as I know the
 potential client side corruption with that, but so far I haven't run into
 that).  I currently have ZIL and prefetch disabled.  I currently limit
 ARC to 2GB as well and set kmem to 4GB (I currently am using FreeBSD 8)
 
 I am up to about 1.5 weeks without a panic now.  The system does a
 constant 80-120Mb/s in read and 30Mb/s write/s during the day and has 9
 NFS clients.
