FWIW, it's still very brittle on Solaris 10 and the Sun Support response to most issues is "restore from backup". The IMHO, the biggest issue with ZFS itself is lack of recovery tools prior to PSARC 2009/479 (in ZFS v21).

My understanding is that the problem is more that the FreeBSD VM system doesn't gracefully handle running low or out of memory. --=20 Peter Jeremy --p4qYPpj5QlsIQJ0K Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.13 (FreeBSD) iEYEARECAAYFAksIVCcACgkQ/opHv/APuIe5xACfagCg4kxJDdcHnSKojHPMLjN6 X/QAn1GiWCsKUkJ8EMiYjnp3rymyE5Uz =TtKp -----END PGP SIGNATURE----- --p4qYPpj5QlsIQJ0K--
