The clients still hang every few hours. There is nothing in the logs.
When we change the rsize and wsize to 2048, the cleint no longer crash but
clients and server because extremely slow.

Please help! We are willing to pay a fee, by the way, if someone is
interested in take a good hard look at our problem.

This is our setup:

SERVER:
=======

Linux Red Hat 7.3 kernel 2.4.18-27.7.x
nfs-utils-1.0.5-1

netboot settings:
label linux
  kernel vmlinuz
  ipappend 1
  append   root=/dev/nfs
nfsroot=192.168.1.112:/clients/%s/root,v3,nolock,intr,rsize=4096,wsize=4096

exports:
/clients/blue/root
192.168.1.160/255.255.255.255(rw,no_root_squash,sync)

CLIENTS:
========

Linux Red Hat 7.3 kernel 2.4.20-18.7custom
nfs-utils-1.0.5-1

fstab:
192.168.1.112:/clients/blue/root                /           nfs
rw,nfsvers=3,hard,intr,udp,nolock   0 0

Hello,

we are also using diskless clients but have never seen something like this,
though none of your hanging programs is running on your systems.
Is there anything in the logs? Which kernel-versions are you using? If you
are
using redhat kernel you should try a vanilla kernel (2.4.21 *NOT* 2.4.22).

Btw, how is your diskless setup working? Perhaps there's something wrong?

Regards,
	Bernd
