internals.AbstractCoordinator {} - Marking the coordinator ip-xyz:9092 (id: 2144 rack: null) dead for group

[shahab <sh...@gmail.com>]

Hello,

And sorry for posting the question again, since I didn't get any response
last time, so I posted it,

I am using Kafka 1.0.1 and in Kafka Consumer side, I am regularly (every
10-20 min) seeing the following Kafka log message which causes the
partition assignment to consumer ,...

Consumer side logs: Marking the coordinator ip-XYZ:9092 (id: 2147482644
rack: null) dead for group MyGroup

Does anyone know what is the source of this issue?

I played with CONNECTIONS_MAX_IDLE_MS_CONFIG  in Consumer side kafka
configuration and it didn't effect the results.

best,
Shahab

Here is the related logs I found in consumer side:
