问题:

I am using spring mvc(annotations). I have written backends. When tasks start running, retry count goes on increasing, It shows status code '503' and message 'service unavailable'. When I hit backend url into browser, I got the same error after hitting many times then getting correct response.

Is there any solution for this..?
