Channel is closed error on Disconnect

I get the channel is closed error on calling disconnect on the SftpClient. Not sure what's happening.

This is the stacktrace of the error

One could consider this a bug in SSH.NET, but I'm inclined to say that you should close/dispose the SftpFileStream or StreamReader/StreamWrter that you obtained by invoking a method on SftpClient before disconnecting.

Can you review your code to make sure you're closing/disposing properly ?

Thanks a lot. There was a Streamreader open. Problem fixed now!
