I never saw behaviour like that, and AFAIR noone told about such problems before. Actually I'm using NFS exported ZFS file systems in production at my company: beast:root:~# zfs get -r sharenfs tank | egrep -v 'sharenfs (-|off)' | wc= -l 28 The load is rather light, but I never seen a single problem. So based on other e-mails in this thread as well, it's seems it's not a well known issue. Any chance you could debug it further? My standpoint is that NFS over ZFS is supported by our port, if that's not true, we should work on this. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
