massakam opened a new issue #2401: Consumer often discards received messages URL: https://github.com/apache/incubator-pulsar/issues/2401 When TLS is enabled, consumer often discards received messages. The following is the consumer log when a message is discarded. ``` 17:53:52.113 [pulsar-client-io-1-1] ERROR o.a.pulsar.client.impl.ConsumerImpl - [persistent://xxx/xxx/xxx/xxx][xxx] Discarding
