Hi,
Oh, I'm sorry. I haven't tested through rpc-cli.
I sent a patch that fix this problem.
In spite of applying the patch, you may see a debug message like this.
DEBUG 2014-07-29 08:40:33,527 speaker 566 Traceback (most recent call last):
File "/home/wataru/ryu/ryu/services/protocols/bgp/speaker.py", line 556, in

evtype, fileno, evtype))
RuntimeError: Second simultaneous read on fileno 13 detected. Unless you
really know what you're doing, make sure that only one greenthread can read any
particular socket. Consider using a pools.Pool. If you do
know what you're doing and want to disable this error, call
eventlet.debug.hub_prevent_multiple_readers(False)
This won't stop the bgpspeaker and it seems the connection will be reset
eventually, but take a little time.
I think this is a bug of eventlet. I'll make further investigation.
Thanks,
