Problem summary
-
**************************************************************** USERS AFFECTED: Any users of MQ clustering, who have installed one of the affected fix packs, are potentially affected by this issue. 9.2.0.20 and later levels of 9.2 LTS are affected. 9.3.0.10 and later levels of 9.3 LTS are affected. 9.3.3 CD and 9.3.4 CD are affected. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A new code branch was added via APAR IT43646 into the affected levels of MQ code. The new branch allowed a Delete of a CLUSRCVR channel to be processed, when this was not correct as per the design. This new branch did not initialise a pointer variable needed later in the code, and therefore it invalidly had a null (zero) value. When de-referenced in the later code, this gave a SIGSEGV.
