Description

The setup of two inter-connected routers is the same as in DISPATCH-358. Let the routers be A and B. Senders connect to A and receivers connect to B. While senders are sending messages to A, restart router B every 10 sec. Senders check tracker status to make sure messages are accepted by the receivers. After running for some time, router A is in bad state. No messages sent are accepted. After that point, I keep router B up without restarting. The problem does not go away. Restart senders and receivers and does not help. I also notice the error in the log:
