--Sig_/pYI3C4R6H+uUIwRHhliBjAt Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable This is the kmem_size overstep issue I'm mostly talking about. No matter how much you tune your system, the chance of a kernel panic due to kmem_size is= too small remains. And the time will come, and you will have a random reboot du= ring the backup procedure. It ofcourse happens when ZFS is in use :) So, in my humble opinion you're better off with (open)solaris for now. There were some posts on a @freebsd mailing list about making zfs more stab= le on amd64 by some VM patching, i don't quite remember the details...

Hrm.
