Error description
You are running CICS V3R1 with CICSPlex SM, and during normal operation, you terminate the logger with FORCE IXGLOGR,ARM. The CMAS terminates due to the logger outage, and requests LRT termination of the MASes and WUI. . The CMAS attempts to restart immediately due to automation, and afterward, the WUI LRT termination completes. The CMAS connection completes, but a series of ABEND 067/AKEB conditions ensue. . The ABEND 067 indicates 'An access register translation exception' in XSRR. The MAS is trying to access a queue dataspace that has been deleted by the CMAS' restart. Additional Symptoms and Keywords: KIXREV(JXD) DFHAP0001 CICSTST2 An abend (code 067/AKEB) has occurred at offset X'FFFFFFFF' in module EYU9XLEV.

Problem summary
**************************************************************** * USERS AFFECTED: All CICSPlex SM V4R1M0 Users * **************************************************************** * PROBLEM DESCRIPTION: A MAS may exerience abend ASRB/S0067 if * * the CMAS to which the MAS is connected * * is terminated abnormally and restarted * * before the MAS is able to terminate and * * enter restart mode. * * * * The abend will most likely occur in a * * method called from method EYU0XQPQ * * (XQPQ), and XQPQ will most likely be * * called from method EYU0XMSM (XMSM) or * * from method EYU0XZPT (XZPT). * **************************************************************** * RECOMMENDATION: After applying the PTF that resolves this * * APAR, all MASes must be restarted. Note * * that the restarts do not need to occur at * * the same time. * **************************************************************** When a CMAS terminates, any MASes that were connected to the CMAS will terminate their MAS agent and enter restart mode. During this time, the MASes will issue messages and may issue exception or level traces: - As part of message processing, XMSM will call XQPQ to write the message to the CMAS's consolidated message log queue, so that the messages can be written to the CMAS's EYULOG. - As part of trace processing, XZPT will call XQPQ to write the message to the CMAS's MAS trace processing queue, so that the messages can be written to the CMAS's auxtrace datasets. Even though the CMAS has terminated, the queues will still exist and be accessible to the MASes. When the CMAS restarts, the storage areas where the queues reside are freed. If the MAS is still issuing messages and/or traces while terminating and entering restart, abends may occur when XQPQ calls a method that attempts to access the freed storage.
Problem conclusion
Method EYU0NLRT (NLRT) has been updated to clear the ID of the consolidated message log queue token from the MSG component's major obect environment block (MOEB) and to clear the ID of the MAS trace processing queue token from the TRC component's MOEB prior to starting the termination and restart processing. When the tokens are cleared, XMSM and XZPT will not call XQPQ to write to the queues.
