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.
