The "pipe closed" indicates that the server you are connecting to has shut down the communications for some reason. Try getting the server log from the Host and see if there are any indications and to why they are shutting down the pipe before the communication is complete.
Also, make sure your resource is set with multiple Retries and Retry intervals ... (5 with 30 sec interval -- or something like that) ... make sure that you're trying to get the transfer completed as best as possible.

You can get more information from that Host Log ... not sure what the issue would be, but it could be just a configuration setting that needs to be tweaked on GADirector when making the connection.
Just like the Retries .. those are options on the Resource configuration.
