Error description
This problem only occurs in CICS for z/VSE 2.2 (430) as distributed with z/VSE 6.2 DFHAP0001 Abend code 0C6/AKEA offset X'FFFFFFFF' in DFHWBBLI Each abend results in an ASRA transaction dump as well as the AP0001 dump. The type of program check can vary dependng on the failing PSW address and could also be 0C1 or 0C4. You might see a similar abend reported at offset x'FFFFFFFF' in DFHWBA. The problem can also affect the CICS Explorer. There might be subsequent abends in other modules and a PC0409 abend that causes CICS to terminate. The problem only occurs when Monitoring is active in the system, i.e SIT MN=ON. This may be dynamically enabled by Vendor CICS Performance Monitors.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: DFHAP0001 Abend code 0C6/AKEA at * * offset X'FFFFFFFF' in module DFHWBBLI * **************************************************************** This problem only occurs when CICS Monitoring in active. That is when DFHSIT MN=ON, or when it has been dynamically enabled by Vendor CICS monitoring software or by the customer. The abend occurs when using CICS Web Services or the CICS Explorer. The same problem may result in an 0C1/AKEA or 0C4/AKEA abend. There might be subsequent abends in other modules, and possibly message DFHPC0409 and a PC0409 abend that results in CICS being terminated. DFHWBBLI incorrectly switches into 24-bit mode after a Monitoring domain call, and the program check is the result of a branch to a bad 24-bit address, hence the various types of program check that can occur. The DFHWBA module has the same problem and needs to be corrected.
Problem conclusion
DFHWBBLI and DFHWBA have been corrected to avoid switching into 24-bit mode.
