-## 可能的原因
服务端的线程资源耗尽了。
-
默认情况下，Dubbo 服务端的业务线程数是 200 个。如果多个并发请求量超过了 200，就会拒绝新的请求，抛出此错误。
+## 可能的原因
+1. Consumer 的并发请求量太大，导致 Provider 端创建的线程数量超限。
+2. 可能 Provider 端在执行业务的时候，由于业务调用外部应用接口，导致线程出现阻塞，从而导致线程池回收不了线程。
+
## 排查和解决步骤
-* 调整 Provider 端的 `dubbo.provider.threads` 参数的大小，调大一些即可。
-* 调整 Consumer 端的 `dubbo.consumer.actives` 参数的大小，调小一些即可。
-* 增加 Provider 端服务器的数量，让各个服务器分担压力。
+* 开启 Dubbo 的访问日志功能，排查是否有短时间内大量调用 RPC 服务的情况。
+* 通过 `jps` 和 `jstack` 指令检查线程池中各个线程的状态，看下是否有业务调用外部应用接口造成阻塞。
+* 如果是 Consumer 的并发请求量太大，那么调整 Provider 端的 `dubbo.provider.threads` 参数，将 Dubbo
的线程池的数目调大。
+* 如果 Provider 业务的 QPS 实在太大，目前的服务器数目处理不完，那么增加 Provider 端服务器的数量，让更多的服务器分担压力。
