IE the client starts a connection and then closes it again without
sending data.
FWIW I've found it easier to reproduce this problem if Ethernet flow
control is off but it still happens with it on as well. This happens
with different types of Ethernet hardware too. The rm -rf isn't necessary
either but makes the problem easier to reproduce (for me anyway).
The mount options are:
# mount | grep u15
sweet.dev.bluearc.com:/u15 on /u/u15 type nfs (rw,noatime,nodiratime,hard,intr,rsize=32768,wsize =32768,proto=tcp,hard,intr,rsize=32768,wsize=32768 ,sloppy,addr=10.1.6.102)
I've generated a stock 2.6.34.1 kernel and that also has the same
problem. We don't encounter this problem with the 2.6.26 package currently
in lenny:
# dpkg --status linux-image-2.6.26-2-amd64 | grep Version
Version: 2.6.26-22lenny1
As this problem is still present in 2.6.34.1, I've posted a message to
http://lkml.org/lkml/2010/7/22/185 as well.
