When usinge the FileOutput node to transfer data over SFTP, it
is possible that the message flow may be rolled back despite the
file having been transferred successfully.
This can happen if the remote host closes the connection after
the file transfer has finished but before the file handle is
closed.
This error is indicated by the following service trace entry:

Problem summary
****************************************************************
USERS AFFECTED:
All users of IBM Integration Bus v10 and IBM App Connect
Enterprise v11 using the FileOutput Node to transfer files using
SFTP.
Platforms affected:
z/OS, MultiPlatform
****************************************************************
PROBLEM DESCRIPTION:
When using the FileOutput node in SFTP mode, it is possible for
a Java exception to occur and roll back the flow despite having
successfully transferred the file. This can happen when the
remote server unexpectedly closes the SFTP connection after the
file has been sent.
Problem conclusion
The FileOutput node will now ignore such Java exceptions once
the file has been successfully transferred.
