Hi,
  could you try this patch with GnuTLS ??

diff --git a/src/tds/net.c b/src/tds/net.c
index 894ab4e..b060ff8 100644
--- a/src/tds/net.c
+++ b/src/tds/net.c

                gnutls_kx_set_priority(session, kx_priority);
                gnutls_mac_set_priority(session, mac_priority);
+               gnutls_record_disable_padding(session);

                /* put the anonymous credentials to the current session */
                tls_msg = "setting credential";

I'm unable to reproduce your problem. I tried to send very long
queries but my GnuTLS version keep sending only 0x1010 bytes per
packet (patch applied or not).

bye
