Additional Symptom(s) Search Keyword(s): IBM MQ V800 We can see that this abend is a good match for an internal defect with identical symptoms that we've fixed very recently. The problem happens during abort processing when reading log records backwards and is a small timing windows where we clear our log properties block prior to resetting the LCIDLRBA field.
