[~arpan.khagram0...@gmail.com] Can you confirm that changing the default config
fixed the issue for you?
{noformat}
replica.fetch.wait.max.ms
replica.lag.time.max.ms
{noformat}
We're also hitting this issue continuously on our clusters, running Kafka
0.10.1.1, and also encountered it (or at least something with the same
symptoms) on our Kafka 0.10.2.1 clusters.
Still need to investigate more in detail what is actually triggering this, so
any tips or insights would be welcome ...

So it must be taking default value as per kafka documentation which is this - replica.fetch.wait.max.ms --- 500 replica.lag.time.max.ms --- 1 (which is 20 times of replica.fetch.wait.max.ms) I am changing my cluster today to updated values as below replica.fetch.wait.max.ms --- 1 replica.lag.time.max.ms --- 20 (which is 20 times of replica.fetch.wait.max.ms) Kindly let me know it should be OK.
