It's possible for stale REQ/DREQ messages to appear at the reset node, but I don't see any problem with that occurring. The DREQs should be dropped, since there's no connections to match them with. The REQs should be rejected without a matching listen. If the listen occurs before the REQ appears, then a new connection would result. I don't see a problem in either case. As for purging stale states, I'm not sure what you mean. The reset node will have purged the local CM state. - Sean _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
