Hi,

I have set up several ibr-dtn nodes with multiple interconnections, without discovery and with static routing. I have defined all possible routes in ibrdnd config files to test path fail-over. When I start dtnping, dtnd crashes after several successful pings. Then ping continues via an alternative route, until the other intermediate node crashes. Sometimes the end node, which is being pinged, crashes first.

I have attached a network diagram, ibrdtnd config files and logs.

I was pinging node 226 from node 224. The route was 224 -> 225 -> 226. The node 226 has crashed. The route changed to 224 -> 227 -> 226. The node 227 has crashed.

Please, advise, what could be done to fix this issue.
