After upgrading z/OS to v2.1, we began to receive the error message IEC999I IFG0TC0A,IGWFARC0,jobname,stepname when selecting the Option Completed (for example) in the first screen of the CA XCOM ISPF Panels. There are no abends.
The XCOM XCOMSTIM (timer) subtask is being detached by our maintask before it has finished its termination process. This problem can arise when XCOM's subtask terminations are delayed by the system.
Please apply PTF RO89224 S13E AND S0C4 ABENDS WHEN USING XCOM API. The description is different than the symptom you are seeing, but the underlying problem is the same.
This fix adjusts the way in which XCOM subtasks get terminated and detached.
