Strange nfs problem

I have a customer with a rather strange NFS problem that I'm just plain
stmped on and I'm hoping that someone might have some enlightening ideas.
Assume the following small network diagram:
OEM System (a)
/ \
/ \
/ \
/ \
/------------\
Fedora RedHat
Core 2 9
(b) (c)
The following NFS scenarios are currently working:
NFS Servers are running on B and C.
File on C, read from A
Write from A to either B or C
Read and write between B and C.
File on B, read from A is causing problems.
The goal is to run software on A from an NFS mounted filesystem on B.
When that transfer is attempted the following has been seen
- The command line hangs and will unlock at the unexport of the NFS
Filesystem.
- The data transfer always results in a file that is exactly 44KB in
Size (45056 bytes)
- Smaller files transfer just fine.
- Files larger than 44KB transfer file; only if they are larger than
some (unknown) upper limit do they block after 44KB.
- Files are 120KB sometimes work, and sometimes block.
Does anyone know what might cause this?
Thanks,
Paul C.
