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

thanks for the update. i am trying to check in broker logs. but non of the 
brokers throwing any exceptions when this error occurred. i am seeing this 
error "ERROR Error when sending message to topic test3R3P3 with key: null, 
value: 4096 bytes with error: 
(org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)
org.apache.kafka.common.errors.TimeoutException: Batch containing 3 record(s) 
expired due to timeout while requesting metadata from brokers for test3R3P3-0" 
every time i run producer.  

producer command - cat kafka_output.log | bin/kafka-console-producer.sh 
--broker-list localhost:9092,localhost:9093,localhost:9094 --batch-size 1000 
--message-send-max-retries 10 --request-required-acks -1 --topic test3R3P3

kafka_output.log has 100000 records of 4096 length each

i see this error even when all brokers are healthy and all partitions have 
valid leaders. 

are you saying brokers restarts internally may be due to load? but when i check 
the UNIX Process ID of brokers before and after running broker, i see the PID 
is same. which means the brokers are not restarted.
