Problem

The IBM Sterling Transformation Extender (ITX) Launcher stops processing Kafka messages if a message is invalid and does not then process any new messages.

Symptom

The ITX Launcher stops processing Kafka messages if a message is invalid and does not then process any new messages.

Cause

Using the ITX Kafka adapter and processing an invalid Kafka message but not using either -ETP or -ERRORTOPIC.

Environment

Using the ITX Launcher with the ITX Kafka adapter as a Launcher source event to process messages on a Kafka topic.

Diagnosing The Problem

The ITX Launcher stops processing a Kafka message while consuming an invalid Kafka message and no further messages are processed.

Resolving The Problem

Use either the -ETP or -ERRORTOPIC parameter with the ITX Kafka adapter to specify an error topic on Kafka so that after encountering an error the listener resumes processing new events.
