    SubjectRe: NFS got stuck on 2.3.22
    Here is a script that reproduces the problem for me.

    I don't know if it requires you to have a double mount (an NFS mount
    under another NFS mount), but it seems to work perfectly in my setup

    Put this script in the exported directory on the server and run it on the

    --- (or whatever) ---


    head -c1m /dev/zero > growfile

    while true ; do
    head -c12 /dev/zero >> growfile


    On the client, cat or cp growfile to /dev/null. Viola. I'm testing this
    over 100 Mbit ethernet with the userspace NFS daemon. The first time I
    tried the "cp", ^C worked after a few seconds. The second time, it
    blocked completely and still hasn't unblocked. "ps l" shows
    "wait_on_page", and "echo 0 > /proc/sys/sunrpc/rpc_debug" shows similar
    output as before.

    My mount options are:

    foo:/ on /foo type nfs (rw,soft,intr,nolock,timeo=8,retrans=8,rsize=4096,wsize=4096,addr=
    foo:/d1 on /foo/d1 type nfs (rw,soft,intr,nolock,timeo=8,retrans=8,rsize=4096,wsize=4096,addr=

    (I was testing in the directory /foo/d1/ ...)
