[Question] <Interface does not work>

### Question

Hi everyone,
I configure 2 interfaces by shenyu-bootstrap, called /a and /b.They are work while single,but /b does not work until timeout while invoked by /a.After timeout, /b works again.
And another scene, I configure 1 interfaces by shenyu-bootstrap which called /a,/a invokes /b.When /b costs long time, /a does not work too.
Who can help me?

Start with the shenyu-bootstrap configuration for the /a and /b interfaces and reproduce both reported call sequences. Trace the timeout behavior when /a invokes /b, then determine whether /b can remain available independently. Done means the cause is identified and the affected request behavior is corrected or clearly documented.
