Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Storage is leaked in the channel * * initiator when client connections * * terminate after putting messages with a * * Message Handle specified in * * MQPMO.NewMsgHandle. Over time the * * leaked storage can lead to storage * * exhaustion and/or performance * * degradation in the channel initiator * * address space. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a client application puts a message, specifying a message handle in MQPMO.NewMsgHandle, storage is allocated for the message handle and associated property control blocks in the channel initiator address space. When the channel terminates this storage is not freed, leading to the storage being leaked.
Problem conclusion
Channel termination processing is changed to correctly free the message handle and associated control blocks for the handle specified in MQPMO.NewMsgHandle. 100Y CMQXRSRV CSQXRMAS
