exception when creating a topo

asked 2017-05-14 20:07:01 -0700

I create a topology with 10 switches and 8 hosts using Python script in Mininet successfully,but ODL throws an exception. I have no idea what it means.

Exception in thread "Thread-89" java.lang.IllegalStateException: Expected state: HANDSHAKING, actual state:RIP

Other topologies can be shown successfully,only this one failed. Can someone tell me what's going on? Thx!
