Warning: The following is a somewhat vague report, given as a fyi. I don't need a resolution on this problem, but wanted to report it. NFS server: Sony VAIO PCG-505TS uname -a: FreeBSD anvil.village.org 5.0-CURRENT FreeBSD 5.0-CURRENT #569: Sat Mar 10 13:17:30 MST 2001 (really Mar 3 current) NFS client: PPro-200 uname -a FreeBSD billy-club.village.org 5.0-CURRENT FreeBSD 5.0-CURRENT #59: Sat Feb 24 14:49:35 MST 2001 The Sony VAIO has a ep0 (3C589E). It has 1 2.5" IDE drive. The PPro has dc0: <82c169 PNIC 10/100BaseTX> on pci0. It has a scsi drive and an IDE drive. I'm seeing about 100kbps on nfs read performance. When I try to copy about 300MB of mp3s like so mount laptop:/mp3 /mnt cd /mnt/path/to/files tar cf - . | (cd /mp3 ; tar xvf -) After about 10 minutes of really bad network performance, the network dies. All network traffic on the server gives errors with no buffers available. netstat -m shows that there are plenty of mbufs available (10% are used). I had to reboot to get the network back. The client survived just fine. I have no clue if I can reproduce this, but thought I'd let people know there might be dragons here.
