I checked with `snoop -v` and indeed I only saw NFS2 requests going over the wire from that specific FreeBSD box. In addition to our AMD maps we statically mount /var/mail; either without any options or when forced to v2/UDP, a 3.2 client hangs now and then when sending mail from Pine. Finally, please note that we are on an extremely bad network with ~10% Ethernet collisions. Perhaps a history might be helpful? 1. 2.2.x clients against a SunOS 4.x host. No problems. 2. 2.2.x clients against a Solaris 2.6 host. No problems. 3. 3.1 clients have long hangs now and then; sending mail with Pine hangs forever now and then. 2.2.x clients are fine. 4. Force v2/UDP for all AMD maps. Both 2.2.x and 3.1 clients are fine. 5. 3.2 clients experience infinite hangs when sending mail with Pine now and then, all others are fine. 6. Force v2/UDP for /var/mail on 3.2 client. No change. Frankly, I feel lost. :-( Any suggestions what I could try?
