We rebuilt kernel-2.6.9-30.EL.src.rpm with the patch from

behavior as before.
Well in my testing the patch in bz182137 did indeed fix
the problem so I'm a little surprised it didn't fix it
in your world...

The problem (that I was seeing) was the GRANT messages being send
by the server are not making to the client do to a bug in
the RPC code. The patch in bz182137 fixes that bug...

So if possible could you please post a bzip2 binary
tethereal network trace capturing the network traffic
when you run your test script. Something similar to:

    tethereal -w /tmp/data.pcap host <server> ; bzip2 /tmp/data.pcap

steved.
