Hi community
My team is faced with a very weird issue and still can't find the cause of
it. Once per two weeks our producers get timeouts during sending
data/metadata into Kafka cluster. In most cases, the issue was with leaders
of the same kafka broker. During this issue, we found nothing in our
monitoring systems for all kafka brokers. Logs had no any errors or unusual
records.
Producers errors like
18-05-11 00:03:47:099 [ERROR] [kafka-producer-network-thread |
producer-1] KafkaSenderLog Error occurred at sending an event to the
bus: error='Batch containing 6 record(s) expired due to timeout while
requesting metadata from brokers for events-1' , key='1' , time=40 ,
event={***}
18-04-29 02:18:17,112 ApplicationMsg=Error occurred at sending an
event to the bus: error='Expiring 1 record(s) for events-8: 5007 ms
has passed since batch creation plus linger time' ,
key='14337/aba54b157688238988054301ba15372b' , time=5018 , event={***}
18-05-09 15:43:56.031 KafkaSenderLog kafka-producer-network-thread |
producer-52 [ERROR] Error occurred at sending an event to the bus:
error='Batch containing 1 record(s) expired due to timeout while
requesting metadata from brokers for tmm_events-6' ,

time=10017 , event={***}
I have removed events content from my listing above. We are using Apache
Kafka 0.10.2.1 with official java Kafka client lib.
I tried to reproduce this with console producer script which comes with
kafka package. I copied our production producers settings and used special
topic with special data rotation settings. I reproduced it. I was getting
timeouts only during sending data and again it was happening rarely and
there were no issues with kafka brokers and their instances.

Could you please help me with this investigation or give some advice which
can help me with this. Thank you
