Error description
GPR 4-7 00000000_2A45660F 00000000_00000010 00000000_FFFFFFF8 00000000_CFD7B140 The CEKL I TAS is looping through transactions. DFHCQSY checks to see if each transactions has a MN TMA, that is monitoring is active, and will be used to determine the CPU time used by the task. In the case when the abend happens it is looking at the tma of user transaction, which was started on 24/08/2022 and has accrued more than 10 and half hours of CPU time (00008CFD7B144C74). The code copies the significant bits of the cpu time into a work field. This is then multiplied by 16(dec) and then divided by 100000 (dec). It is this division that causes the 0C9.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: Abend 0C9 in DFHCQSY. * **************************************************************** A CICS region has been active for many months and has a long running transaction accumulating CPU time. A CEKL INQUIRE TASK is issued from the console and it will attempt to calculate the total CPU time used by all transactions. The CPU time accumulated by the long running transaction is so large that the result cannot be accommodated in a 32 bit register and DFHCQSY abends with an abend 0C9.
Problem conclusion
DFHCQSY has been changed to use a 64 bit field for CPU time.
