我的应用程序在x时间后崩溃，一个mongo db收集了大约150000个文档。
我的应用：nginx - phusion-passenger - node.js
在这个应用程序中，有一个函数可以查找带有verif日期的文档（date.now - 4h）并更新返回的文档。
但是应用程序崩溃了，错误：

此键<String[11]: oldpricearr>是一个数组：
[{price: 5445, date: isodate},{price: 5468, date: isodate},{price: 45121, date: isodate},{price: 4785 date: isodate}, ect..];
此文档是否已损坏？或者这个docs中的数组对于推送新元素来说太大了？ 如何找到问题？
