      Description

      In Genilex AWS system test process, we found the following two situation:
      1. After long time without sending request to esp, if client send request, esp will get cannot connect to ELB error; after restart esp server, the error is gone.
      2. During middle of the stress test, esp will get cannot connect to ELB error, the rest of the request will failure;
      when we setup esp, we use ELB DNS name to configure the connection between esp and elb;
      after esp start, esp server will parser DNS to get ip, and keep this ip in system until the next time to restart the esp. But in AWS system, elb will be recycled, and the ip of elb will be changed dynamically.
