Question & Answer
Question
Why would all my CICS Transaction Server for z/OS (CICS TS) regions on same SMS plex started receiving 0C3 AKEA abends at startup? The regions initialize successfully so the abend doesn't appear to have any impact on the regions. This is the message I'm receiving:
DFHAP0001 An abend (code 0C3/AKEA) has occurred at offset X'FFFF' in module DFHSUWT.
Answer
To format the Kernel domain of a system dump of the AP0001, you can enter IPCS command VERBX DFHPDxxx 'KE=1' (where xxx is your release level of CICS like 700 for CICS TS 5.3).
In this case, the dump shows the task running in error is CSSY.
The KE domain error table shows the following:

Program DFHSUWT was in control, but the PSW was elsewhere.
Error happened under the CICS RB.

The failing CSSY task fails with the abend0C3 EXECUTE exception in CAS9EVT #CA-ENF# (at 0C46420). The failing EXECUTE instruction (at 00C46D2E) is attempting to execute itself, thus abend0C3 occurred.
CA ENF/CICS was trying to initialize in regions with no products that make use of this facility. After ENF was disabled in CICS the abend 0C3/AKEA no longer occurred.
