MongoError: write EPIPE

Question

我正在使用 Node.JS + Mongoose + MongoDB。直到现在我的应用程序运行正常，现在尝试保存文档时：

保存操作：

doc.save(function(err, d){
    console.log(err,d);

{"name":"MongoError","message":"write EPIPE"}

错误堆栈：

{ [MongoError: server localhost:27017 received an error {"name":"MongoError","message":"write EPIPE"}]
  name: 'MongoError',
  message: 'server localhost:27017 received an error {"name":"MongoError","message":"write EPIPE"}' } undefined
error: TypeError: Cannot read property 'url' of undefined

看来我可以读取数据，但不能写入新文档。 Mongo 是应用，运行。到目前为止我已经尝试过，重新启动数据库，但没有很好的结果。

刚刚尝试从 mongo 客户端插入并成功了

> db.mysecretcollection.insert({url:"sampletestremoveme"});
WriteResult({ "nInserted" : 1 })

所以这似乎是一个 Node.js / Mongo 问题。

Answer 1

在我看来，文档太大了，实际上我在删除其中一个字段后能够保存它。奇怪的是，猫鼬应该用 "Error: Document exceeds maximum allowed bson size of XXX bytes" 异常捕获它，但它从未被抛出。
