I met such problem while I was making some changes.Could you help me classify it?
I want to simulate the hardware,so I send messages from a border router to the others .At first it is ok,but after a few while with no messages sent,the next few time I send messages from a border router to the others,it is quite easy to go wrong.I think this has something to do with alivenodes.

Big brother,your kindness will help a poor student who is making painstaking efforts to make a simulation system about openthread. Your help will also make openthread more popular in China!!
