issue in ServerAsyncWriter : C++

[Chaitanya Gangwar]

Hi All,

I have implemented Async streaming server and to post data to client i am using ServerAsyncWriter api. I am facing a issue in this api in below mentioned scenario :

- Server is up and running
- clients are connected and at a specified timer, i am posting data to clients

- from other thread i shutdown the grpc server, and before calling shutdown on Server and completionQueue, i call FINISH() on ServerAsyncWriter  and set the CallData state as FINISH.

- As soon as FINISh() api is called on ServerAsyncWriter , server completionQueue recieves a notification and i call proceed on the returned tag.

-- Since CallData state is FINISH now, i am deleting my CallData object.

- But the issue is, that after calling FINISH on ServerAsyncWriter , my server completionQueue is receiving 2 events on for same CallData and proceed is called twice causing double deletion.

- I am not sure why my completionQueue is receiving 2 events, is it a desired behavior or am i missing something. 


**GRPC version  : 11

Thanks
