• Fixed an issue that prevented ServiceNow from communicating with the Kafka bridge for Podman users.
• Fixed an LSN persistence issue that caused some messages to leak into Kafka.
• Fixed a problem that triggered resending of all Kafka messages after a restart.

• This interim fix prevents ingestion of outdated data from the PostgreSQL database into the Kafka broker, ensuring that duplicate messages are not sent during restarts.

The Fix Pack archive (1.4.2-ZRDDS-IF0001.tar.gz) for xLinux on amd64 and zLinux on s390x includes the following files:

• kafkaconnect-1.4.2-amd64.tar
• kafkaconnect-1.4.2-s390x.tar
• 1.4.2-ZRDDS-IF0001-README.txt
• swap_kafka_connect.sh
• clear_kafka_topics.sh
• utils/

To prevent old data from being sent to Kafka, apply the fix by performing the following steps:

1. Upgrade to version 1.4.2-ZRDDS-FP001. For upgrade and deployment instructions, see Deploying Z Resource Discovery Data Service.
2. Extract the 1.4.2-ZRDDS-IF0001.tar.gz file, and run ./swap_kafka_connect.sh.
3. Run ./clear_kafka_topics.sh to clear Kafka topics and messages.
4. Restart the system to confirm if Kafka is clear of messages.
