I hope ENOMEM errors are not related to your panic, because on ENOMEM GEOM should repeat the request a bit later. Will be good to know if you have simlar panics without graid3. For example on a plain disk, but with 2kB sector size (you can do it with gnop(8)). You can also try gstripe(8) your disks with small stripesize, eg. 512 bytes and use gnop(8) on top of it to change sector size, so all disks will be used, in case there is a problem with your controller. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
