Ok, here's some more goodies.. Netstat -s looks fine.. On the server, a netstat -a shows: Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 2392 0 otter.nfsd netman.1009 ESTABLISHED Server's name is otter and netman is the solaris 7 client (using autmounter to use the nfs share). The server is running FreeBSD 4.6.2. And I've attached a small tcpdump (-w filename.txt -vvv host netman) run from the server to capture the "trigger". It's only a few packets, but these are the packets that make it go bad. Also, I'm running nfsd on the server like so: nfsd -h ip.of.nic.1 -h ip.of.nic.2 -t -u -n 10 If I run nfsd like: nfsd -h ip.of.nic.1 -t -u -n 10 it works fine. It isn't a bad NIC on the server (I've tried multiple nics, mutliple servers, and different FreeBSD OS versions) - but it could possibly be a bad NIC on the client side. What other data do you need? Heck, if I need to, I'll set up a "test bed" that you can access, and we can go from there.
