The connection is getting closed by the server. RST is being sent to the client from virtual server after 5 minutes of the download starting while data is flowing.
This affects FTP transfer of large-sized files that take more than 5 minutes (the default idle timeout in TCP profile on the BIG-IP system) to download.
If the settings for the TCP profile are default on BIG-IP then this issue will be encountered for FTP transfer of files that take longer than 5 minutes to download. In a general case, if the idle timeout in the TCP profile is less than the keep-alive interval, and if FTP transfer takes more time than the specified TCP timeout, transfer gets interrupted.
Set the timeout to Indefinite or set the keep-alive interval to a value that is larger than idle timeout in the TCP profile. Then download does not get interrupted and completes as expected.
