Question

mongodb版本：2.6.0

收集字段：

books{
       _id,
       chatpers : [    //a book has many chatpers, so the "chatpers" is an Array.
                    { 
                        _id,
                        _parentId,
                        text
                     }
                   ]
}

我运行的查询是：

db.books.update({
    _id : ObjectId("5354725719980e913e9be3f1"),
    "chapters._id" : "93cdb3d14da841aabde0dd65aa2fa343"
}, {
    "$set" : {
        "chapters.$.text" : "5.3 Handler",
        "chapters.$._parentId" : "ef5c3f14147f417b936221db00deff38"
    }
});

问题：当章节长度很小时，效果很好。当章节的长度超过120+时，mongodb报告错误，然后关闭：

2014-11-04T18:44:00.759-0700 DBClientCursor::init call() failed
2014-11-04T18:44:00.761-0700 Error: error doing query: failed at src/mongo/shell/collection.js:416

非常感谢你的好意！
