Hi, t.conch.ssh.filetransfer.FileTransferClient._sendRequest keeps a mapping with active SFTP requests in self.openRequests
The self.openRequests is only updated when the server is responding for that request. They are not cleared/cancelled on connection lost. In the case in which the client send a request in the exact same time in which the server closes the connect , the client will send the request as there is no way to know that the server is gone... but since the server is gone it will not reply to the response... and the deferred is never called. To solve this issue, I went for cancelling the open requests when the connection is close. I assume that this is also an issue with bad behaved servers which will just ignore a request... so instead of a simple deferred, there is the need to use a timeout deferred. Is this a bug? I am wondering if I am doing something wrong and these type of errors should be handled in a different way. Thanks!
