Any ideas what could be causing this issue?
If you're seeing that a different cookie was sent in the response than the one in the request, it means the server went down and the request had to be redispatched. This should be clearly visible in the logs. You will see one request with flags "NI--" going to test-app-west-1, then probably a few requests with flags "VN--" going to it, then one request with either "DI" (server down) or "VI" (server was not yet known as down but connection failed and was redispatched).
