Bill,
Have you removed the sys(3050) call to be see if the header corruption is really caused by that command?

And have you noticed a substantial improvement in performance? I ask this because we found no improvement at all, although we were using a different network setup. We had no header corruption, but the command was not left in the system for long since it gave us no improvement.
