Description

The HandleHttpRequest shutdown process includes attempts to clear the queue of pending requests and send HTTP 503 responses. The current implementation polls the queue with a timeout of two seconds and attempts to send responses to retrieved requests. Uncaught RuntimeExceptions can result in failing the empty the queue, resulting in unexpected request processing when HandleHttpRequest is rescheduled to run.
