FWIW, I've seen it a few more times on two different machines. Both running semi-new FreeBSD (I still don't think I ever saw this on earlier CURRENT:s). In the case of both machines, the machine is only selectively hung. Possibly limited to the zfs file system - definitely not global to the pool. A remote reboot -q -n has been useful to recover without console access. In both of these cases, more or less all activity of any amount is on ZFS file systems. One of them has only ZFS except for swap on a UFS file system. The other has root on UFS, but no bulk operations whatsoever happening (beyond the usual periodics) except on ZFS. No NFS on either machine. -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller@infidyne.com>' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.8 (FreeBSD) iEYEABECAAYFAkgx47IACgkQDNor2+l1i30cowCfTLnFFuqxUjTfeqXh9Ji+e4Bu I7EAoMY5EnKrEWmZZvrxqZRzhU39Y1/K =X4HK -----END PGP SIGNATURE-----
