Weird grpc error: address already in use

[windmemory]

I've observed this weird log today, the grpc server failed to start itself since the address has been bind. Let's keep an eye on this problem.

This is caused by multiple io-client process running at the same time. And seems like when the puppet is crashed or stopped, the io-client process is not stopped for some reason.

Still need more investigation on this issue.
