Same thing is reproduceable on RH AS 3.0 AMD64 with the same version 
nfs-utils package.

Comment 2 Steve Dickson 2005-06-17 18:00:42 UTC
hmm...  the server kernel version,  2.4.21-27.EL.re3.4GB, appears
not to be build in our internal build system... So where did this kernel
come from and what, if any, modification were made?

Comment 3 Venkat Reddy 2005-06-17 18:18:17 UTC
This is a custom kernel. But the same thing happen on the following system too. 

[root@qa1 root]# uname -a
Linux qa1 2.4.21-4.ELsmp #1 SMP Fri Oct 3 17:32:58 EDT 2003 x86_64 x86_64 x86_64
[root@qa1 root]# more /etc/redhat-release 
Red Hat Enterprise Linux AS release 3 (Taroon)
[root@qa1 root]# rpm -qa | grep nfs

Comment 4 Kevin Krafthefer 2007-01-23 00:50:40 UTC
This needs to be reproducible on fully patched clients and servers.

Comment 5 RHEL Product and Program Management 2007-01-23 01:01:13 UTC
Product Management has reviewed and declined this request.  You may appeal this
