Yes, it sure does. The only thing that should block between those output messages is getting the messenger lock, which *ought* be fast. Either there are a lot of threads trying to send messages and the heartbeat thread is just getting unlucky, or there's a mistake in where and how the messenger locks (which is certainly possible, but in a brief audit it looks correct). -Greg -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
