Hi Alex, Sorry for the delay. I was not able to reproduce the problem; it looks like you are running on Windows, in which case gRPC's fork handlers are not registered/run, so those shouldn't be the cause here . Since the reproduction example also uses CherryPy websockets, it's quite possible the issue stems from that software rather than the gRPC stack - we'd likely need a reproduction case that only uses gRPC, without the websockets, to be able to help debug this further.
