Mongoose MongoError：拓扑被破坏

我在MongoError中运行“拓扑被破坏”不时。 我的应用程序使用nodejs，mongodb，mongoose（4.1.3），express（4.13.3）。

要连接到服务器，我使用以下参数：

var con = mongoose.createConnection(baseUri, { server: { poolSize: 1 }, socketOptions: { keepAlive: 1, connectTimeoutMS: 10000 }}); 

这就是我在日志文件中find的：

 /data/var/www/rk/node_modules/mongoose/node_modules/mongodb/lib/server.js:235 process.nextTick(function() { throw err; }) ^ MongoError: server localhost:27017 received an error {"name":"MongoError","message":"read ECONNRESET"} at null.<anonymous> (/data/var/www/rk/node_modules/mongoose/node_modules/mongodb/node_modules/mongodb-core/lib/topologies/server.js:265:47) at g (events.js:260:16) at emitTwo (events.js:87:13) at emit (events.js:172:7) at null.<anonymous> (/data/var/www/rk/node_modules/mongoose/node_modules/mongodb/node_modules/mongodb-core/lib/connection/pool.js:77:12) at g (events.js:260:16) at emitTwo (events.js:87:13) at emit (events.js:172:7) at Socket.<anonymous> (/data/var/www/rk/node_modules/mongoose/node_modules/mongodb/node_modules/mongodb-core/lib/connection/connection.js:121:49) at Socket.g (events.js:260:16) at emitOne (events.js:77:13) at Socket.emit (events.js:169:7) at emitErrorNT (net.js:1253:8) at doNTCallback2 (node.js:441:9) at process._tickCallback (node.js:355:17) 

谁能告诉我这个错误是什么意思，我怎么能解决它？

谢谢！！！
