WellaceZ edited a comment on issue #1564: Provider停机过程中，consumer的新请求报The request is rejected和Failed to send request, local:not connected问题 URL: https://github.com/apache/servicecomb-java-chassis/issues/1564#issuecomment-583367429 另外还有个问题，Provider停机时，在等待现有线程（存在耗时任务）处理这个过程中： ### 【问题3】由于Provider实例自身是STOPPING的状态，那么耗时任务如果想调用另一个Provider（自身作为Consumer）的接口，将无法调用成功，这个问题要怎么处理？ 日志如下： 2020-02-07 17:56:22.922|WARN |a2266adca6534011a51021b6d65b3ec3||[pool-3-thread-1]|AppInterceptor.java:delFailed:218|service param error. org.apache.servicecomb.swagger.invocation.exception.InvocationException: InvocationException: code=503;msg=CommonExceptionData [message=The request is rejected.
