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. Weldon ----- End forwarded message -----
