We are trying connect SFTP server to transfer 20KB file.

The SFTP connection stuck during the file transfer and SFTP server neither releasing connection nor receiving the file.



We can see connection successful and welcome message from server afterwards.The following message keep coming up
DEBUG [ChannelDataWindow] 29 Aug 2012 07:22:00.284 : Waiting for at least 50 bytes of window space


Appreciate your help in this regards.

It looks like a known bug that is fixed in a later release. Upgrade to 4.2.0.

Your log says "edtFTPjPRO-3.1.1" so you're not using the version you think you are.
