Error description
For COBOL programs using ACCEPT ... FROM SYSIN, the run-time fails to free the buffers allocated for SYSIN when the enclave terminates. This is generally harmless, but if for some reason enclaves are repeatedly created and destroyed, the buffer leak can cause an out of memory problem below the line.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: Enterprise COBOL V5+ users running programs * * that ACCEPT from SYSIN, or DISPLAY upon * * SYSPUNCH, the programs are called from * * non-LE assembler repeatedly, and the LE * * Enclave that the COBOL program is executed * * is terminated. * **************************************************************** * PROBLEM DESCRIPTION: Memory leak/Short on storage ABEND: * * The DFSMS buffer for the SYSIN or * * SYSPUNCH was not released at the LE * * Enclave termination processing. If * * such a COBOL program was repeatedly * * called from a non LE ASM program, this * * could cause the LE Enclave to be * * initialized and terminated for each * * call, and a memory leak would occur. * * Depending on the user program's memory * * requirements, this could cause an out * * of memory condition/short on storage * * condition. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** At LE enclave termination, FREEPOOL is used to release storage allocated by DFSMS for ACCEPT from SYSIN, or DISPLAY upon SYSPUNCH.

Problem conclusion
LE enclave termination processing has been corrected.
