You're likely hitting the ulimit. Edit /etc/security/limits.conf andallow the rabbitmq user to have a much higher "nofile" setting. Rabbitwill log on start up how many sockets it's permitting, so once thechange has taken effect and you've restarted rabbit, you should findlog entries to demonstrate it's working.

虽然我可以提高这个限制，但我宁愿关闭未使用的连接。是否有一种方法可以使在一定时间内未使用的连接过期？

我通过打开心跳解决了这个问题:

https://github.com/pika/pika/blob/master/pika/heartbeat.py

params = ConnectionParameters(host='127.0.0.1', heartbeat=True)
connection = BlockingConnection(params)

这样，如果连接中断，服务器会处理关闭它。
