Pre-check

• I am sure that all the content I provide is in English.

Apache Dubbo Component

Java SDK (apache/dubbo)

Details

Why, when I used the Dubbo reactor mode in the provider, did I find that Dubbo is still running in the Dubbo handler thread pool? Under high concurrency, it still reports errors indicating that the thread pool is full.
I user dubbo 3.2.14 ，jdk 17

client send request -> server -> parse request -> submit threadpool -> adapting reactor invoke

In triple, after receiving the request, it will try to submit it to the thread pool for execution, and handle the adaptation of the reactor in the thread pool.
