But when producer send queue is full, pulsar websocket server ProducerHandler throws errors: Error occurred while producer handler was sending msg from /127.0.0.1:37254: org.apache.pulsar.client.api.PulsarClientException$ProducerQueueIsFullError: Producer send queue is full. On the java websocket client side, it still receive result ok ack from server: {"result":"ok","messageId":"CPEKEINF","context":"1","errorCode":0,"schemaVersion":0} from server To Reproduce Steps to reproduce the behavior:

1. Launch pulsar standalone and java websocket client connecting pulsar websocket server producer endpoint.
2. keep publishing messages until producer send queue is full. Pulsar websocket ProducerHandler throws errors.

@xqianwang Hi, can you add more detailed info about how to set up websocket client to reproduce this issue ? I am using cmd bin/pulsar-client produce <topic> -n 1000 -r 1000 and sets brokerServiceUrl=ws://localhost:8080/ in conf/client.conf. Not able to reproduce this issue.
