Both runni= ng=20 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. Possibl= y=20 limited to the zfs file system - definitely not global to the pool. A remot= e=20 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 f= ile=20 systems. One of them has only ZFS except for swap on a UFS file system. The= =20 other has root on UFS, but no bulk operations whatsoever happening (beyond= =20 the usual periodics) except on ZFS. No NFS on either machine. =2D-=20 / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller ' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org --nextPart1830900.nYTVAVdTCr Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.8 (FreeBSD) iEYEABECAAYFAkgx47IACgkQDNor2+l1i30cowCfTLnFFuqxUjTfeqXh9Ji+e4Bu I7EAoMY5EnKrEWmZZvrxqZRzhU39Y1/K =X4HK -----END PGP SIGNATURE----- --nextPart1830900.nYTVAVdTCr--
