@SatishKumarL5551   could you confirm your version of Kafka?

----------------------------

Kafka has known issues on windows environment.  

Pega did addressed this issue by update the kafka version.

The kafka version kafka_2.11-1.1.0.5, which is default in Pega 8.5.4  have taken care of the issues.

There is a local change. However my recommendation will be to wait and apply if the issue is frequent. 

Until 8.6 Pega has uses two compacted topics: __consumer_offsets and df_run_metrics. Covert these two topics to the not compacted topics:

<Check your kafka version>

$./<kafka-1.1.0.5>/bin/kafka-topics.sh --zookeeper localhost:2181 --topic __consumer_offsets --alter --config cleanup.policy=delete $./<kafka-1.1.0.5>/bin/kafka-topics.sh --zookeeper localhost:2181 --topic df_run_metrics --alter --config cleanup.policy=delete
