   We met the same problem in PyFlink (Based on beam portability framework). It took me some time to locate and reproduce the problem. The root cause is that the BDP ping period is locally-decided. We can reduce the KEEP_ALIVE_TIME time on the server side or increase the grpc.keepalive_time_ms on the client side. Here is the PR of the modification I made in pyflink
