Poluect commented on issue #2431: Unable to consume messages, need to re-subscribe client
URL: https://github.com/apache/pulsar/issues/2431#issuecomment-569348450
 
 
   Hello! We started using Pulsar instead of Kafka in our system, and currently facing the same issue, when few subscriptions (like 1 - 3 of 30) stop receiving messages, and they get stuck in a backlog, until either a subscriber, or pulsar proxy restarted. 
   
   We are using version 2.4.2, with 3 brokers in a cluster. Issue appears pretty often, like 3 - 6 times in a day. Stats also attached. Hope this issue can be fixed or at least hope there can be any workaround except of force deleting kube pods with subscriptions to make them reconnect. We used Kafka to handle some critical parts of our system, unfortunately we can't rely on Pulsar without having simplest consumer - producer scenario work well. Thank you!
