Detailed Description and Symptoms
Message "U0011018 Host: 'HostName' is reporting status for inactive FT: 'RunID'" showing in Messages window after a successful file transfer.
If this is immediately after a successful file transfer, then it is likely just a timing issue. What is happening is while one WP is processing and completing the transfer, another WP checks the status of the FT within a small window after it finishes and sees the data record as completed but still reporting - hence reporting on an inactive file transfer. As long as there were no issues with the file transfer itself, then this message is nothing to be concerned about.
