Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: 0C4 at Offset x'4970' in DFHLDDMI * * during warm restart. * **************************************************************** During a warm restart all the previously installed programs are read from the catalog. This causes CPE control blocks to either be created or reused. If DFHSIP was one of these previously installed programs CICS attempts to reuse the already created CPE. If there is an active APE chained from this CPE this is freemained. When the APE is freed the pointer is nulled The APE pointer is then attempted to be used to find the next APE on the chain causing the 0C4 to occur.
Problem conclusion
DFHLDDMI has been changed to save the next APE pointer before freemaining the current APE.
Temporary fix
