Xml 当我更新文本时，Orion会关闭

这里描述的错误发生在最新版本的Orion上下文代理和Mongo服务器上

有时它会在数据库中生成实体，但总是转到mongo

检查您使用的MongoDB版本。Orion支持MongoDB 2.4。请编辑您的问题以包含以下信息，好吗？1） contextBroker版本（通常使用

contextBroker--version

），2）MongoDB版本，3）您最近更新过contextBroker吗？4） 如果3是肯定的，哪一个是旧版本？谢谢此外，我还需要进一步了解这个案例。。。因此，您可以使用RESTClient执行问题帖子中显示的updateContext，并在问题帖子和这些日志消息中获得XML响应。对吗？猎户座在哪一刻关闭了？发送响应后？请在更新到0.20.0之前运行哪个版本？您是在更新过程中删除了数据库，还是在不接触数据库的情况下开始使用新的Orion版本？因此，为了清楚地理解它，您的意思是您从scractch安装了0.20.0，而没有从以前的CB版本（如0.19.0、0.18.0等）升级？
