我正在经历一个奇怪的问题.我的控制器调用drb对象
@request_handler = DRbObject.new(nil, url) availability_result = @request_handler.fetch_availability(request, @reservation_search, params[:selected_room_rates])
这个Drb对象正在进行一些搜索.
但有时候,在linux环境中,我得到了一个带有这个堆栈跟踪的"0xdba87b30是回收对象"

奇怪的是,我无法在我的(windows)开发机器中重现错误,但我只在我的linux测试服务器中得到它(2个mongrels而不是我的机器中的一个).
怎么了？我认为这是一个垃圾收集器问题(重用之前收集的对象),但我不明白我做错了什么.我只需在控制器中创建对象并在其上调用方法.
任何的想法？
谢谢!罗伯托
该错误意味着您正在尝试提供垃圾收集的对象,这通常是因为该对象超出了服务器上的范围.
你最安全的赌注是弄清楚为什么对象过早被垃圾收集.或者,您可以通过调用禁用服务器的GC GC.disable,这通常是一个坏主意,特别是如果您的服务器长时间运行.
