We have the same issue with Ganymed and Wing FTP Server. We have tried upgrading Wing FTP Server to 4.0.5, but this has not solved the issue.
What we see is a series of "Remote sent too much data, does not fit into window." errors with a few seconds in between.
The client is SSH-2.0-Ganymed-build260 and the server is Wing FTP Server 4.0.5.
This error occurs frequently (many times per day) and is a huge problem. Is this a known issue and are there any workarounds to it?
Kind regards, Mads
