Is this issue still present in kernel 2.6.15?
This bug happened for me over NFS too. Hardware Environment: 2-Dual core AMD Opteron , 4GB RAM Software Environment: RHEL 4 SMP kernel. Process g++ while trying to write over NFS.

2.6.9 is awfully old. This might well have been fixed in the intervening year or two. It would be more appropriate to take this up with Red Hat, sorry.
Does it still occur with kernel 2.6.16.5? Otherwise (as Andrew already said), please contact RedHat for support with this issue.
Please reopen this bug if it is still present in kernel 2.6.17.
