the invalid sequence of command is typical when the client requests a file transfer, then tries to issue normal commands in the control channel. Until the data connection either times out from no activity or is aborted, all commands (except NOOP and ABOR) will result in the invalid sequence. From the logs the server is still waiting for the fxp to connect but the client starts issuing size and retr commands again without waiting for the status of the previous transfer request
