high nfs load after rsync finishes

[Daniel Widyono]

Only thing I can think of is some interaction with memory.  NFS buffers in
memory and that memory might be taken away during the rsync which is also a
memory hog.  Check memory usage before, during, and after rsync to see if
this is a possibility.

If the above theory is true, these actions should not help.
