Closed as program error.
If DataPower establishes an outgoing SFTP connection and the backend becomes unresponsive during a transaction, the connection might not close.
Affected are customers using DataPower with a SFTP backend. When the SFTP server being connected accepts the TCP connection, but immediately stops responding, the TCP connection will not timeout, leaving the TCP port open and the memory allocated for the transaction. TCP ports in this state can be recovered without an appliance restart when the affected TCP connection is terminated (e.g. by the server itself or external injection of a RST packet).
Fix is available in 220.127.116.11, 18.104.22.168, 22.214.171.124 and 126.96.36.199. For a list of the latest fix packs available, please see: http://www-01.ibm.com/support/docview.wss?uid=swg21237631
