concurrent requests through nginx's grpc_pass failed

When sending grpc requests through nginx concurrently, I received at client:

Caused by: io.netty.handler.codec.http2.Http2Exception$StreamException: Cannot create stream 2015 greater than Last-Stream-ID 2001 from GOAWAY.

When requesting grpc server directly without nginx, there is no error.

http://nginx.org/en/docs/http/ngx_http_v2_module.html

The behavior is controlled by http2 module, not grpc module:

    http2_recv_buffer_size 1024k;
    http2_max_requests 2147483647;
    http2_max_concurrent_streams 200;
