获取配置块时出现警告消息

Question

在尝试从Orderer获取配置块时，我们在Orderer端获得了以下警告，尽管我们能够成功获取块。任何人都可以告诉我们为什么这条警告信息来自Orderer方面？我们可以放心地忽略它吗？

2019-03-18 05:37:47.304 UTC [common.deliver] Handle -> WARN 020 Error reading from 127.0.0.1:48474: rpc error: code = Canceled desc = context canceled
2019-03-18 05:37:47.304 UTC [comm.grpc.server] 1 -> INFO 021 streaming call completed {"grpc.start_time": "2019-03-18T05:37:47.295Z", "grpc.service": "orderer.AtomicBroadcast", "grpc.method": "Deliver", "grpc.peer_address": "127.0.0.1:48474", "error": "rpc error: code = Canceled desc = context canceled", "grpc.code": "Canceled", "grpc.call_duration": "8.871178ms"}

Answer 1

这个警告通常是良性的。它表示客户端在获取块后没有正常关闭流gRPC连接。
