> This can indicate that all consumer for this provider has been shutdown, which means no one can request current server.
But the consumer server keeps running。
Although it does not affect calling，But I feel that this will generate frequent socket connections

Same here. The consumer keeps disconnecting and reconnecting about every 3 minutes. Any help?

If the consumer keep running, provider should not print connection closed message except connection lose, which may be caused by heartbeat failed or registry push.
