我正在使用DocumentDb v1.8.0，当检查集合是否存在时，它将返回404错误。如果我收到该错误，我会尝试创建该集合，并返回409错误（资源已存在）。
我有四个集合，其中一个集合在每次完成此检查时随机失败。数据库/集合没有被删除，所以我不知道为什么会发生这种情况。
其他一些信息：
使用stacktrace更新：

在一个静态构造函数提供程序类（每个Db一个）中创建的IReliableReadWriteDocumentClient有两个实例，用于查找两个集合。
UPDATE2： 进一步研究，将请求与地址路由表进行比较，ReadCollection方法（404s）以主节点为目标，但CreateCollection方法（409s）以二级节点为目标。 我也在工作，不幸的是可能需要一点时间。
