rabbitmq pika连接错误

Question

pika.exceptions.StreamLostError: Stream connection lost: ConnectionResetError(104, 'Connection reset by peer')

报以上错误

send.py

import pika
import sys
import time
import json
from pymongo import MongoClient

# 远程rabbitmq服务的配置信息


# 消息队列服务的连接和队列的创建
credentials = pika.PlainCredentials(username, pwd)
connection = pika.BlockingConnection(pika.ConnectionParameters(ip_addr, port_num, '/', credentials,heartbeat=0))
channel = connection.channel()
channel.queue_declare(queue='ws_interface', durable=True)


for x in co.find({"state": 0}).limit(100000):
    print(count)
    count += 1

   
    channel.basic_publish(
        exchange='',
        routing_key='ws_interface',  # 写明将消息发送给队列balance
        body=pub_dict,  # 要发送的消息
        properties=pika.BasicProperties(delivery_mode=2, )  # 设置消息持久化(持久化第二步)，将要发送的消息的属性标记为2，表示该消息要持久化
    )  # 向消息队列发送一条消息
    print(" [%s] Sent 'message!'")
    # time.sleep(0.2)
connection.close()  # 关闭消息队列服务的连接

receieve.py

import pika
import json
import time
import os

credentials = pika.PlainCredentials(username, pwd)
connection = pika.BlockingConnection(pika.ConnectionParameters(ip_addr, port_num, '/', credentials, heartbeat=0))
connection.process_data_events()
channel = connection.channel()

channel.queue_declare(queue='ws_interface', durable=True)


# 消费成功的回调函数
def callback(ch, method, properties, body):
    # 调用任务链，产生ES-log，便于统计和展示。这里mq的价值在于，可水平扩展，增加节点来增加消费速度
    body = json.loads(body)
    time.sleep(7)

    print(" [%s] Received %r" % (time.time(), body))
    # time.sleep(0.2)
    # 具体逻辑

    # 当工作者完成任务后，会反馈给rabbitmq
    channel.basic_ack(delivery_tag=method.delivery_tag)


# 开始依次消费balance队列中的消息
channel.basic_consume(on_message_callback=callback, queue='ws_interface', auto_ack=False)

print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()  # 启动消费

简单的说就是send 10w个自增id ，消费打印出来，如果加上 time.sleep(7)
就会报错
这怎么解决

Answer 1

channel.basic_qos(prefetch_count=1)

加了这个 不会报错了，有没有大佬帮忙分析一下问题出在哪儿
