Troubleshooting

If you encounter issues while enabling Kafka, use the troubleshooting tips explained in this topic.

EDI BP executes slowly

BP takes long time to execute when you enable Kafka Visibility on the system and execute EDI X12 or EDIFACT enveloping/de-enveloping operations.

Workaround/Solution: If Kafka Visibility is enabled, check if the brokers configured are accessible, which means the Kafka cluster is up.

If Kafka cluster is down, then the following message is displayed in Kafka logger file (kafkaviz.log).


logs (kafkaviz.log). Async API is enable

ERROR [KafkaMessageCallback] Timeout has occcured while sending message to kafka. Check the setting buffer.memory or max.block.ms

EDI events not seen in Kafka Topic

No events appear in Kafka Topic when you enable Kafka Visibility on the system and execute EDI X12 or EDIFACT enveloping/de-enveloping operations.

Workaround/Solution: If Kafka Visibility is enabled, check the following configuration:

Topic name is configured correctly in the eventsnosql.properties file.
Configured Topic exists in Kafka
Configured brokers are accessible, which means the Kafka cluster is up

If Kafka cluster is down, then the following message is displayed in Kafka logger file (kafkaviz.log).
