Could this be an issue with the driver on this release for em0?=20 Possibly - there have been some issues with em(4) and some chipsets. Alternatively, it could equally well have been a glitch on the associated switchport. >b.) Why was I not able to ssh to the client servers while the NFS server w= as down? Logging into a client entails filesystem accesses and if any of those filesystems are NFS mounted then those accesses will block if the NFS server is non-responding. Note that by default, sshd will search /lib, /usr/lib and /usr/local/lib (as well as subordinate compat libraries) to dlopen() nss modules - which means that a local root and /usr could still block if you have a NFS mounted /usr/local. --=20 Peter Jeremy --ctP54qlpMx3WjD+/ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAkydKLwACgkQ/opHv/APuIdDbQCfXmBeIu7anymyZSaVjLlvqqj+ QIIAn3SsHCnr6Sel+TkXoQRTeqJ7qdYA =j/ZK -----END PGP SIGNATURE----- --ctP54qlpMx3WjD+/--
