      Description

      In SCPFscaleTopo test, I use arping to let onos discover host instead of pingall. When I established 20x20 tour topology, and send 1 arp package from each hosts, onos will crash, the topology will be lost. Sometimes it will happen when onos discovered around 200 host, but sometimes it will happen early.
      Also, the onos log report some warning:
