Problem summary
**************************************************************** * USERS AFFECTED: * * All users of IBM MQ for z/OS Version 9 Release 0 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: * * Storage leak may occur when an SSL/TLS channel fails to * * start. May eventually lead to chinit abending S878 RC10. * **************************************************************** * RECOMMENDATION: * **************************************************************** When an SSL/TLS channel fails to complete its connection, a small amount of associated storage containing distinguished names for certificates may not be released. When these failures are frequently occurring (e.g. due to channel retry), then eventually the storage leak may lead to an S878 RC10 abend in the channel initiator address space.
Problem conclusion
Processing has been amended to ensure that associated storage is released when an SSL/TLS channel fails to connect.
