Could you please check in procstat -kk -a if there are any threads in zio_wait call. Also, you can send the full output to me privately. - -- Andriy Gapon -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.16 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJMw+qLAAoJEHSlLSemUf4vbmcH+gIQuRqqs/UQBmiYaIFQFMk0 BsmPxPxr0N8gI7s7m2wlumYxnLv8Yvi8+0h0+GwHvdpHzz8xGe5W9/FO3ONt9dc/ jCPzbGd9kMypHASTDKgsGowIg3q07TICjKkKquJ3eIxS4BItHMRYmjQLceYISXZ6 qkCzUIqyUWCkSa6Ja+0/8LbJvxAce+Fp5Msc/A8Fjls85QM81sSWqFWEGluYCbFN /SkGSIWJrOWEgLxiyMNyrlMgVHj3ASfaUwb9eN7VCcGQjVZwYSJ15gnHnjjSRpJ6 Osk69wk3Wowddm+vaacrijWrHCnN/+fJ83d3fVCeUvlQ/dADhfiM8wEm6AtarY8= =H+hR -----END PGP SIGNATURE-----
