We have an issue where producer is timing out writing to a kafka topic. The timeout set is 30 seconds. I dont see any specific errors related to the topic in kafka logs but i see the below errors during that time. What could be the issue ? How can i go about debugging this ?

We tried to restart Kafka increase the timeout for replication threads. At this point we are stuck on how to proceed further. Any help is greatly appreciated.
