The AICA abend can occur if the kernel notify task has no locally connected MASes and has no need to broadcast the events. If no plex broadcast is necessary, the XLNX task should suspend to avoid a possible AICA abend.

Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM V4R1M0 and V4R2M0 Users * **************************************************************** * PROBLEM DESCRIPTION: Abend AICA may occur in a CMAS in * * method EYU0XLNX (XLNX), or a method * * called by XLNX, when a large number of * * CPSM events (for example, EMASSICK, * * EMASWELL) are being processed in a CMAS * * network in a short period of time. * * * * This abend is more likely to occur in a * * CMAS that has no MASes connected to it. * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all CMASes must be restarted. Note * * that the restarts do not need to occur at * * the same time. * **************************************************************** When an event is issued for a MAS, XLNX in the CMAS that is connected to the MAS will deliver the event locally to other methods and then issue a broadcast to deliver the event to all CMASes in the network that manage the CICSplex associated with the MAS. XLNX will then run in the partner CMASes, delivering the event locally only. When a large number of events occur in a short period of time, it is possible that XLNX will be busy beyond the ICVR value for the CMAS. Since the originating CMAS issues a broadcast which will cause the task to suspend, it will not AICA. However, the partner CMASes do not issue a broadcast, and thus could abend AICA.
Problem conclusion
XLNX has been updated to call method EYU0XSSP (XSSP) to issue an EXEC CICS SUSPEND when processing a large number of events in a short period of time, if it does not issue a broadcast.
