Could anybody please help me with the question originally posted on stackoverflow?

I have a grpc service written in C# which has 2 calls like Start and Stop. When a client calls Start (this call takes much time) and then Stop server processes requests synchronously while grpc has started 4 threads.

2016-12-01 18:55:14,199,INFO,grpc 2 (cq 2),0 parsing.c:659: HTTP:17:HDR:SVR: :path: /Service/Start

2016-12-01 18:55:14,303 [grpc 2 (cq 2)] DEBUG [RPC:27] Start 2016-12-01 18:55:14,822,INFO,grpc 0 (cq 0),0 parsing.c:659: HTTP:19:HDR:SVR: :path: /Service/Stop 2016-12-01 18:55:33,661 [grpc 2 (cq 2)] DEBUG [RPC:27] Stop

These log messages shows that request was received by grpc 0 but was processed by grpc 2 after Start has been finished.

Could you please help me to understand if it functions as designed or maybe I have missed any additional settings?

I am not sure I understand the question correctly. Please provide more information. What platform is this? What gRPC version are you running? Are server and client different processes?

From your description, it is not clear to me if something's wrong.

It is Windows, grpc 1.0.0 and server and client in different processes

It seems that completion queue is assigned per channel (per client) so all requests from the same client are processed synchronously. Can I change this behavior without client reconnection per each call?
