HystrixRuntimeException: TestCommand fallback execution rejected

I am using Hystrix 1.5.5 version. When I do load testing of bigger load like 1000 thread/second, all the requests are going through fallback method. Meanwhile, I am getting below exception too. Why do I get this below exception. Test Command is my custom Hystrix class

Caused by: com.netflix.hystrix.exception.HystrixRuntimeException: TestCommand fallback execution rejected.

You need to check on the maxConcurrentRequests value for both execution & fallback. Below url discusses on this issue.
