=====================================================================

The RunID 181775637 is the RunID of the FT carried out that also correctly transferred the file.
The size of RunID 2147479552 does not fit in the customer system at all, but it does cause the FT to be aborted.
This error occurs only on MVS Agent with version 12.3.5 that are used for FileTransfers.

 

Environment

Release : 12.3 Component : Z/OS Agent

Cause

This is a bug of the Z/OS agent detected in version 12.3.5.

 

Resolution

This bug will be fixed in the following versions:

Automation.Engine 12.3.9, available 

Automation.Engine 21.0.3, available 

Additional Information

A bug has been fixed where the Reverse connection file transfer between Windows(S) and z/OS(D) causes Windows agent crash, because z/OS agent sends a corrupted FTXSEND message, where codepage dist/len fields are in big endian instead of little endian format.
