From the Message and Codes manual:
Explanation: A command has failed due to a serious failure in a CICS component (resource manager).
System Action: The transaction is abnormally terminated with abend code AEXZ. CICS takes a transaction dump, unless module DFHDUIO is not loaded.
User Response: Use the transaction dump to determine the cause of the failure. For further assistance, or if module DFHDUIO is not loaded and no transaction dump is available, contact your system programmer.
It sounds like you either need to read a dump to find out the problem, or contact your site support group.
