Error description
During the process of decompressing a message which has been PUT, the uncompressed message fits exactly into the remaining space of its buffer, however the compressed data length was not divisible by 4 and so was later padded to a word boundary by the sender.

Problem summary
**************************************************************** * USERS AFFECTED: All Users of IBM MQ for z/OS Version 9 * * Release 1 Modification 0 and Release 2 * * Modification 0 * **************************************************************** * PROBLEM DESCRIPTION: FFST in rriDecompress, resulting in a * * SVRCONN channel failing with * * MQRC_CONNECTION_BROKEN. * * * * The FFST indicates that the failure is * * due to RRCE_BUFFER_INVALID, however the * * buffer appeared to contain all of the * * correct data. * **************************************************************** During the process of decompressing a message which has been PUT, the uncompressed message fit exactly into the remaining space of its buffer, however the compressed data length was not divisible by 4 and so was later padded to a word boundary by the sender. The decompressing procedure continued beyond the original message length, resulting in the FFST as the buffer was full.
Problem conclusion
Processing has been amended to ensure that there is enough room to process any padding bytes that may have been added after message compression.
