Typically references from NFS to the underlying file system
even after unexport come from file locks.
To verify that, try mounting from the clients with nolock.
If you cannot do without locks, figure out
is that your client workload includes locking,
and theirs do not.
Please try with nolock on the client side,
and see if that changes something.
