当 node.js 服务器处于非活动状态一段时间后,它会崩溃并出现以下异常:
events.js:72
throw er; // Unhandled 'error' event
^
Error: failed to connect to [------] at null. (/Users/tomi/Documents/Platforms/Databox/Sources/Web/server/node_modules/mongoose/node_modules/mongodb/lib/mongodb/connection/server.js:636:74)

这就是我初始化连接的方式:
function connect(uri, poolsize, callback) {
var options = {
db: { native_parser: false, retryMiliSeconds: 5000, numberOfRetries: 360000 },
server: { poolSize: poolsize, socketOptions: { keepAlive: 1, connectTimeoutMS: 5000 }, auto_reconnect: true }
};
this.connection = mongoose.connect(uri, options).connection;
var addEvents = function (obj) {
obj.on('connected', function () {
console.log('Connected to database');
//connectionPoolStats.logConnectionPoolStats();
});
obj.on('disconnected', function () {
console.log('Disconnected from database');
});
obj.on('close', function () {
console.log('Connection to database closed');
});
};
addEvents(this.connection);
if (callback) {
callback();
}
};
连接只是抛出异常并且永远不会重新初始化;(
有什么线索吗?
