This can occur due to insertion of correlation id’s in MQ headers. Applications with strict MQ message validation may reject MQ messages with altered headers.
This can be addressed by disabling MQ header insertion. By default, the MQ header insertion property is enabled in MQPP. It will enable the MQ header insertion for MQRFH2 and JMS headers. It is needed to correlate MQ connector calls with other Java components. If it is disabled, then the correlation between the traces might not happen properly. To disable the MQ header insertion, make the following change in the MQAgent.properties file.
After making these changes, the MQ Agent will need to be restarted.
