Yes, I Am! My test machine is still running the bonnie++ loop that i've started on friday, with only vfs.zfs.arc_max=512M in loader.conf. Seems pretty stable. I'll retry just one more time without the vfs.zfs.arc_max tunable to see if it's going to panic again. - -- Regards, Nikolay Denev -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (Darwin) iEYEARECAAYFAkkqc3EACgkQHNAJ/fLbfrn3uQCeIBwfLIRYcA1/BaR8mxAy5yX0 pW4AoIhH93PIUhTN+cnqTXMHJY0OnAoU =KpHs -----END PGP SIGNATURE-----
