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?
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 GNU/Linux [root@qa1 root]# more /etc/redhat-release Red Hat Enterprise Linux AS release 3 (Taroon) [root@qa1 root]# rpm -qa | grep nfs redhat-config-nfs-1.0.13-1 nfs-utils-1.0.5-3
This needs to be reproducible on fully patched clients and servers.
