Hyperledger fabric错误：14 UNAVAILABLE：TCP写入失败

Question

当链码容器保持空闲一段时间后，它会因错误而停止：

ERROR [lib/handler.js] Chat stream with peer - on error: "Error: 14 UNAVAILABLE: EOF\n    at createStatusError (/usr/local/src/node_modules/grpc/src/client.js:64:15)\n    at ClientDuplexStream._emitStatusIfDone (/usr/local/src/node_modules/grpc/src/client.js:270:19)\n at ClientDuplexStream._receiveStatus (/usr/local/src/node_modules/grpc/src/client.js:248:8)\n    at /usr/local/src/node_modules/grpc/src/client.js:804:12"

当第一个请求在空闲时间之后出现时，它会给出错误

Error: 14 UNAVAILABLE: TCP Write failed

之后第二次请求错误更改为以下内容：

Error: SERVICE_UNAVAILABLE
at ClientDuplexStream.broadcast.on (/app/node_modules/fabric-client/lib/Orderer.js:172:22)
at emitOne (events.js:116:13)
at ClientDuplexStream.emit (events.js:211:7)
at ClientDuplexStream._emitStatusIfDone (/app/node_modules/grpc/src/client.js:236:12)
at ClientDuplexStream._receiveStatus (/app/node_modules/grpc/src/client.js:213:8)
at Object.onReceiveStatus (/app/node_modules/grpc/src/client_interceptors.js:1290:15)
at InterceptingListener._callNext (/app/node_modules/grpc/src/client_interceptors.js:564:42)
at InterceptingListener.onReceiveStatus (/app/node_modules/grpc/src/client_interceptors.js:614:8)
at /app/node_modules/grpc/src/client_interceptors.js:1110:18

从第三次请求开始，一切正常。

我使用的是fabric-shim 1.2.0，但在将其升级到1.3.0后，错误随机出现。

我正在使用fabric 1.3.0。

编辑：将Fabric Shim升级到1.3.1后，错误更改为以下内容：

error: [Orderer.js]: sendBroadcast - on error: "Error: 14 UNAVAILABLE: TCP Write failed\n    at Object.exports.createStatusError (/app/node_modules/grpc/src/common.js:87:15)\n    at ClientDuplexStream._emitStatusIfDone (/app/node_modules/grpc/src/client.js:235:26)\n    at ClientDuplexStream._receiveStatus (/app/node_modules/grpc/src/client.js:213:8)\n    at Object.onReceiveStatus (/app/node_modules/grpc/src/client_interceptors.js:1290:15)\n    at InterceptingListener._callNext (/app/node_modules/grpc/src/client_interceptors.js:564:42)\n    at InterceptingListener.onReceiveStatus (/app/node_modules/grpc/src/client_interceptors.js:614:8)\n    at /app/node_modules/grpc/src/client_interceptors.js:1110:18"

这个问题似乎与grpc版本更改有关，可以尝试使用稳定的grpc版本
