Tue 12 Jun 2007 03:26:43 PM UTC, comment #4: I'd be happier with the 2*MSS rather than MSS. When you first reported the problem I thought 2*MSS was right, but didn't like to question you and didn't have time to look it up. It's probably something to do with interaction with the delayed ACK mechanism, or Nagle, or something like that.

When heavily opening and closing the tcp receive window on one side of a TCP connection, I ran into the problem with the TCP sstresh value being set to 0 resulting in a stop of transmission. My interpretion of the TCP standards (carefully studying of TCP/IP Illustrated) is that sstresh never should be assigned a value less than one MSS. Adding zero value check to the code solved all the transmissions stops.
