看来这意味着您的节点服务器与MongoDB实例的连接在尝试写入时已中断。
看一下产生该错误的Mongo源代码
Mongos.prototype.insert = function(ns, ops, options, callback) {
if(typeof options == 'function') callback = options, options = {};
if(this.s.state == DESTROYED) return callback(new MongoError(f('topology was destroyed')));
// Topology is not connected, save the call in the provided store to be
// Executed at some point when the handler deems it's reconnected
if(!this.isConnected() && this.s.disconnectHandler != null) {
callback = bindToCurrentDomain(callback);
return this.s.disconnectHandler.add('insert', ns, ops, options, callback);
}
executeWriteOperation(this.s, 'insert', ns, ops, options, callback);
}
这似乎与注释中引用的Sails问题无关,因为未安装任何升级来加速崩溃或“修复”
