Error description
You are running CICS Transaction Server 3.1 and receive the following message: DFHSM0131 CICS is under stress (short on storage below 16MB) Looking at the dump you see the CDSA contains most of the storage below the line. Looking further into the subpools contained in the CDSA you see KESTSK24E is the largest. This contains CICS stack storage for cics modules. In this case these stacks represented module DFHTIEM, which is defaulting to using a stack below the line. This APAR is taken to possibly make DFHTIEM use a stack above the line.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All * **************************************************************** * PROBLEM DESCRIPTION: CICS can go short on storage below the * * 16Mb line trying to obtain KESTK24E * * storage for DFHTIEM's stack. * **************************************************************** * RECOMMENDATION: * **************************************************************** CICS can go SOS for below the line storage. DFHTIEM defaults to SMODE(24) for its stack storage. On a system with a constrained DSA, many concurrent tasks attempting to acquire TIEs for the RMI can lead to an SOS condition. KEYWORDS: FIN defect 21041
