Error description
DB2DDF DB2TCPIP defect pm93896 dpm93896 Abend 00E20003, 00E20013 reported from DIST address spaces. The dump shows all storage is allocated for control blocks RAIM and RAIE, block size x'1000' each. IFCID 165 trace records will show numerous freadinfaddrinfo and getadinfaddrinfo eyecatchers VSM report in the dump will show biggest consumer storage in SP251 Key7 and eyecatchers as noted ************************************************************** Additional Symptoms and Keywords: ABEND04E AB04E S004E 04E 04E-00E20013 00E20013 RC00E20013 DSNSLD1.DSNSGMN+05CA DSNSLD1 DSNSGMN+05CA DSNSGMN +05CA 04E-00E20003 00E20003 RC00E20003 DSNLXPAL.DSNSVBK+0606DSNLXPAL DSNSVBK+0606 DSNSVBK +0606 DB2STGLK/K

Problem summary
**************************************************************** * USERS AFFECTED: All Distributed Data Facility (DDF) users. * * Especially those that utilize TCP/IP * * communications to access remote locations * * from DB2 for z/OS requesters or use * * trusted connection processing with * * inbound client connections. * **************************************************************** * PROBLEM DESCRIPTION: Possible symptoms may include: * * - ABEND 04E-00E20013 * * at DSNSLD1.DSNSGMN+05CA * * - ABEND 04E-00E20003 * * at DSNLXPAL.DSNSVBK+0606 * **************************************************************** * RECOMMENDATION: * **************************************************************** A DB2 for z/OS DDF requester will always need to request name resolution services from TCP/IP if the IPADDR column in an SYSIBM.IPNAMES row is a domain name, as opposed to an IPv4 or IPv6 address. A DB2 for z/OS DDF server will always need to request name resolution services from TCP/IP if a domain name is provided in the context definition of a trusted inbound client connection. The name resolution service involves two calls to TCP/IP. The first call causes TCP/IP to acquire storage in the DB2 ssnmDIST address space that contains the required information. Once the information is processed by DB2, the second call causes TCP/IP to free the storage that it acquired. DB2 corrupted the storage address provided to TCP/IP during the second call. As a result, the storage is not freed which causes a storage leak leading to various Short On Storage related symptoms.
Problem conclusion
DB2 has been changed to ensure the storage address it obtains via any TCP/IP name resolution service request is subsequently passed back to TCP/IP during the free name resolution service resources requests.
