The addition of these two lines to net/sunrpc/xprt.c:xprt_reconnect(),
somewhere between 2.4.10 and 2.4.18, is probably what fixed it:

        if (xprt_connected(xprt))
                goto out_write;

+       if (sock && sock->state != SS_UNCONNECTED)
+               xprt_close(xprt);
        status = -ENOTCONN;
        if (!(inet = xprt->inet)) {

If you can't upgrade the client kernels (2.4.9-34 is no longer the latest
errata kernel for any RedHat version, was replaced by 2.4.18-19.7.x), then
forcing all rh7.x clients to use UDP mounts should cure the problem.
