NFS errors linking large executables

I have a snap server and operating as a NFS file server.

I mount the snap partitions on the following machines: a Fedora Core 2 box,
a Fedora Core 3 box, and a box running RedHat 7.1. The core 2 and 3 boxes
are running relatively upto date kernels. The RedHat 7.1 box is running
an original kernel.

The NFS file system work 99% of the time. However on the Fedora Core 2
and 3
boxes I experience errors when linking large programs. When I link
large programs
and write the executable directly to the NSF partion the executable will
not run (core dumps, won't even get past _start() ); I'll call this case
a. If I
take the same object files (which reside) on the snap server and
direct the linker's output to the local hard drive, then
the executable works fine; I'll call this case b. I can even move
the executable from case b to the NFS partition and it still works fine.
If I diff the executables I see that about 40 bytes in case a
(out of 2MB) in the executable are zero compared to what is present in
case b.
[The overall sizes of the executable from case a and b are identical.]
I do not see this problem when using my older RedHat 7.1 box.

I have tired to increase the rsize and wsize parameters in /etc/fstab as
well as
trying both nsf client versions 2 and 3. The error is present in all cases.
When I try compiling smaller programs things work fine on all three boxes.

The snap server is running SnapOS version 4.0.837. The Core 2 box is
running
kernel 2.6.9-1.6_FC2smp, the Core 3 box is running 2.6.10-1.741_FC3, and
the RedHat
box is running kernel 2.4.2-2.

Any help, suggestions, etc would be most welcome.
