window size shrinks until it gets to 0 and session times out (wodSFTP / wodSFTP.NET / wodSFTPdll)

Large file transfers to an important customer are repeatedly failing. The trace shows SFTPLib.NET sending smaller and smaller window sizes until it gets to a window size of zero, which causes the session to eventually timeout. We were using version 3.4.9.132, but also tried the latest version 3.4.9.134. The transfers work with CoreFTP.
