Problem summary
**************************************************************** * USERS AFFECTED: All Distributed Data Facility (DDF) users. * **************************************************************** * PROBLEM DESCRIPTION: The following intermittent abends are * * reported: * * o 04E-00E20006 DSNLZRTM.DSNSVBK +096A * * or various other offsets (V9). * * o 04E-00E2000F DSNLZRTM.DSNSVSFB+0858 * * or various other offsets (V10). * * In either case, DB2 will likely * * abnormally terminate with message * * DSNV086E and reason 00D94001. * **************************************************************** * RECOMMENDATION: * **************************************************************** A DB2 for z/OS allied thread happened to be abnormally terminated, in this case via a U0999-00000000 abend, while CSECT DSNLZRTM was in the process of freeing DDF related storage. As a result of the abend, the allied thread enters abort processing but a residual pointer value causes the storage to be freed again. The erroneous double free of the storage is detected in the form of an abend 04E-00E20006 DSNLZRTM.DSNSVBK (V9) or 04E-00E2000F DSNLZRTM.DSNSVSFB (V10). The abend during abort processing causes the subsystem to be terminated with message DSNV086E and reason code 00D94001.
Problem conclusion
DB2 has been changed to anticipate that its processing may be interrupted and hence clear pointer references to its storage as the storage is being freed. This ensures that a free of the storage cannot be repeated if processing is interrupted.
