Rall的Dalli网络错误

Question

我正在我的测试服务器中运行以下问题，我已经对网站进行了memcached，但有时它会抛出错误页面。以下是错误的描述。我google搜索它没有得到任何解决方案。错误：

Cache read: http://test.server.in/? test-cache.example.amazonaws.com:11211 failed (count: 0) RuntimeError: Cannot share client between multiple processes
 #<Dalli::NetworkError: Socket operation failed, retrying...>
retrying request with new server
