Ok, I tried panic, it gave a page of the typical panic page that this crash generates under 7.0. I rebooted and no core, so I am missing a step. Sorry for being clueless here. Since the panic didn't reboot, I did a bt, it said process it was at process 1001 access.nfsrv and access.nfs3srv (sorry, I know that isn't quite right, I meant to write it down, it was definately something with access and nfsrv) Thanks, Weldon If memory serves me right, sometime around Yesterday, Jeremy Chadwick told me: > On Thu, Aug 21, 2008 at 03:35:04PM -0400, Weldon S Godfrey 3 wrote: >> Looks like the bug with NFS and ZFS still exists. >> >> Well, I got the lastest 8-HEAD on with the most recent ZFS patch and ran >> the benchmarks again this morning and after about an hour, it paniced >> with the same message about page fault with nfsd.
