One more exception I got in my application is as follows:
SEVERE [grpc-server-app-9] io.grpc.internal.SerializingExecutor.run
Exception while executing runnable

Above exception was thrown while closing stream after successful completion
of rpc at server side. But, how to debug for above behavior since the
thrown exception isn't seen everytime on stream close action? What could
have caused this issue?
