What version of gRPC-Java are you using?

1.49.0
Also grpc-kotlin 1.3.0

What is your environment?

MacOS 12.5.1 with OpenJdk 17.0.2
Ubuntu 18.04.3 with OpenJdk 17.0.3

What did you expect to see?

GRPC NettyServer is configured with maxConnectionAge of 1 second and maxConnectionAgeGrace of 300 seconds. Client sends requests with large response size (4 MB). Client receives responses successfully.

What did you see instead?

Eventually the client throws io.grpc.StatusException: UNAVAILABLE after receiving GOAWAY from the server. We first saw this behavior with large request size on our production and testing environments running on Linux. Then we were able to reproduce using a minimal project with large response size on MacOS.

Steps to reproduce the bug

• Clone the project from https://github.com/usischev/grpc_poc
• Run the main() function in Main.kt, or ./gradlew run
• There are blocking and coroutine (kotlin) server and client configurations in the code, see README.md. All configurations trigger the exceptions eventually.
• Error logs can be seen in https://github.com/usischev/grpc_poc/tree/master/logs
