流星的CollectionFS下载错误：写完后

此问题仅出现在生产阶段，开发阶段-就像魅力。

当用户尝试通过帮助程序生成的链接下载文件时：

<a href="{{fileRef.url download=true}}">Download</a>

在服务器端，node.js失败并forever重新启动它，并产生以下错误：

Error: write after end
   at ServerResponse.OutgoingMessage.write (_http_outgoing.js:413:15)
   at ServerResponse.http.OutgoingMessage.write (packages/meteorhacks:inject-data/lib/server.js:56:1)

   at process._tickCallback (node.js:355:11)
error: Forever detected script exited with code: 1
error: Script restart attempt #1

我想在客户端上文件只能部分下载-只有第一块。我们试图更改nginx反向代理缓存，缓冲设置，甚至关闭-完全没有帮助。

任何想法如何解决，或在哪里寻找错误？任何帮助都非常感谢。

集合初始化代码：

path = (if (NODE_ENV is "development") then "/uploads/Addresses" else "/builded/bundle/programs/server/assets/app/uploads/Addresses")

Collections.Addresses = new FS.Collection 'Addresses', 
   stores: [ 
      new FS.Store.FileSystem 'Addresses' ,
        path: path
   ]
,
  filter: 
    allow: 
      extensions: ['xls', 'xlsx']

if Meteor.isServer
  Meteor.startup ->
    Collections.Addresses.allow
      insert: (userId) ->
        return checkFunc userId
      remove: (userId) ->
        return checkFunc userId
      update: (userId) ->
        return checkFunc userId
      download: (userId) ->
        return checkFunc userId

  Meteor.publish 'Addresses', (ProjectID) ->
    check ProjectID, Mongo.ObjectID

    if checkFunc this.userId
      Collections.Addresses.find 
        'metadata.project_id': ProjectID
    else
      throw new Meteor.Error 403, 'Permission denied'
