C++ Graceful server shutdown

[shikhach...@gmail.com]

Hello , 

gRPC version : 1.0.0

9 pthreads are created during server startup (equivalent to the cores available). I am following  the follwing sequence to shutdown the server : 

- server_->shutdown()

- cq_0>shutdown()

The above sequence stops listening at the mentioned IP:Port combination but somehow isn't cleaning those existing pthreads even when streaming / GET request is in progress.

Please suggest if i am missing some shutdown step & also could you redirect me the relevant piece of code responsible for server shutdown. I checked server.cc, dynamic_thread_pool.cc all logic appears fine.

-Thanks

Typo : Even when no connection is in progress

Do you mean you created 9 threads or grpc created 9 threads?

I assume you are working on an async grpc server? Are those threads your rpc handling threads?

grpc creates some threads internally to do some work offload.
