Ruby dhtmlxGrid可编辑网格错误号：ECONRET

我对Ruby和Rails非常陌生

我使用rails 3.0.9和ruby 1.9.2

我使用了本页所示的dhtmlxGrid：

在网格中添加和删除一些条目后，我随机得到以下错误： “错误Errno:ECONNRESET:远程主机关闭了现有连接

C:/Railsinstaller/Ruby1.9.2/lib/ruby1.9.1/webrick/httpserver.rb:56 in 'eof?'

C:/Railsinstaller/Ruby1.9.2/lib/ruby1.9.1/webrick/httpserver.rb:56 in 'run'

C:/Railsinstaller/Ruby1.9.2/lib/ruby1.9.1/webrick/server.rb:183 in 'block in start_thread'

服务器不会立即崩溃。而是在一些完成的GET请求后随机崩溃。然后，我从Windows收到一个错误，我的Ruby解释器（CUI）1.9.2p290崩溃

如何避免这种不稳定？

我的模型如下所示：

class Timestep < ActiveRecord::Base

has_many :prodcaps, :dependent => :destroy
has_many :demands, :dependent => :destroy
has_many :maxaddcaps, :dependent => :destroy
has_many :addcapcosts, :dependent => :destroy
validates :stepnumber,     :presence   => true
attr_accessible :stepnumber

end

class TimestepsController < ApplicationController
 def view
 end
 def data
     @timesteps = Timestep.all()
 end
 def dbaction
     #called for all db actions
     stepnumber = params["c0"]

     @mode = params["!nativeeditor_status"]

     @id = params["gr_id"]
     case @mode
         when "inserted"
             timestep = Timestep.new
             timestep.stepnumber = stepnumber
             timestep.save!

             @tid = timestep.id

         when "deleted"
             timestep=Timestep.find(@id)
             timestep.destroy

             @tid = @id

         when "updated"
             timestep=Timestep.find(@id)
             timestep.stepnumber = stepnumber
             timestep.save!

             @tid = @id

     end
 end
end

xml.instruct! :xml, :version=>"1.0"

 xml.tag!("rows") do
   Timestep.all.each do |timestep|
     xml.tag!("row",{ "id" => timestep.id }) do
         xml.tag!("cell", timestep.stepnumber)
     end
   end
 end

将应用程序部署到heroku后，此错误不再发生。 在我看来，这只是韦德里克的问题
