Issue:
When the z/OS Agent is started with the default ini parameter (parameter LISTEN without a value) and the Job monitor UCXJM25M is utilized (UC_EX_JOB_MD=UCXJM25M) for job status tracking, the AE does not recognize any job status changes.
The agent-log shows the error message:
 
"EDC8127I Connection timed out."

Normal job tracking is blocked and jobs may have status "Vanished" in AE.


 
Environment:
z/OS agent V12.1.1
Job monitor: UCXJM25M
Cause:
Defect. The 12.1.1 version of the z/OS agent is shipped with parameter "LISTEN=" instead of "LISTEN=10"
Resolution:
Solution:
The default ini has been fixed in version 12.1.2 or above of the z/OS agent. 

Workaround:
Set the LISTEN parameter to LISTEN=10 or remove it completely from the ini-file
