    raise DeadlineExceededError(str(err))
    DeadlineExceededError: ApplicationError: 5


    gae的各种悲剧,各种超时,蛋疼的蛋蛋都有裂纹了。
    请问有什么好的解决方法么?
    支付啊,paypal支付啊,稳定点,行不?

    ApplicationError 5的问题一般是达到限制的上限,例如数据库每秒每Root Entity只能写入5次,每秒urlfetch次数不能超过5次。
    这是GAE的硬限制,花钱也解决不了。
    所以我很怀疑GAE真的能支撑一个大型应用网站吗?

    感谢楼上的热心,问题找到了,不是你说的那样
    是urlfetch gae deadline 默认是5 ,最大是10
    我修改成10 就没问题了
    我全局修改的
    修改方式参见:http://jjinux.blogspot.com/2011/06/python-increasing-timeouts-for-urlfetch.html
