FWIW, i'm having some nfs issues too. i have a openbsd file server and am mounting on linux. it used to work ok, then in the last couple of months it stopped working. on the client, if i do "ls -R" on the mount point, it prints out a couple thousand files and then stops printing any more. i found mounting with nfs version 2 to be a workaround: hostname:/data on /mnt/bunny type nfs (rw,vers=2,tcp,addr=192.168.xyz.abc)
