> URL: https://issues.apache.org/jira/browse/ARROW-15793
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++, FlightRPC
> Reporter: Yibo Cai
> Priority: Major
>
> Normally the test finishes in 100ms. But it often costs 10s on my test
> machine.
> Debug build is good.
> I did brief debug, looks it's related to
> [https://github.com/apache/arrow/pull/12302].
> It stuck 10 seconds in destructing grpc::Server at code
> [https://github.com/apache/arrow/blob/master/cpp/src/arrow/flight/server.cc#L863]
> To reproduce:
> {code:bash}
> $ cmake -GNinja -DARROW_BUILD_TESTS=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo
> -DARROW_FLIGHT=ON ..
> $ ninja arrow-flight-test
> $ relwithdebinfo/arrow-flight-test --gtest_filter="*DoPutLargeBatch*"
