Hi,
sometime my program is normally work, but sometime it hang up.
when i get switch object, sometime it 's hangup and later it show error
message.
*command:*
PYTHON=. ./bin/ryu-manager --observe-links ryu/app/address.py
*my program as follow:*
@handler.set_ev_cls(event.EventLinkAdd)
def link_add_handler(self, ev):
link = ev.link
self.logger.info("link add: %s",link.to_dict())
linkarray = link.to_dict()
src_sw = api.get_switch(self, link.src.dpid)[0]
dst_sw = api.get_switch(self, link.dst.dpid)[0]
src_dp = src_sw.dp
dst_dp = dst_sw.dp
src_parser = src_sw.dp.ofproto_parser
dst_parser = dst_sw.dp.ofproto_parser
*error message:*
hub: uncaught exception: Traceback (most recent call last):

i think get_switch function is the point.
but i don't know how to correct it.
Thanks,
Ping
