AAO4
Explanation
DFHZARL, or a module called by DFHZARL, has detected a logic error. This error is almost certainly caused by the module receiving invalid data or indicators from VTAM.
System action
Before returning to the CPI Communications layer, DFHZARL calls DFHZNAC to clean up the session and put out messages on the CSNE log. CPI Communications abnormally terminates the transaction with a CICS transaction dump, and produces an exception trace entry.
User response
Check the CSNE log to determine the type of error. You may need further assistance from IBM to fully resolve this problem. See Working with IBM to solve your problem for guidance on how to proceed.
