Eric Leu created DISPATCH-368:
---------------------------------
Summary: Router in bad state in two inter-connected routers
Key: DISPATCH-368
URL: https://issues.apache.org/jira/browse/DISPATCH-368
Project: Qpid Dispatch
Issue Type: Bug
Components: Routing Engine
Affects Versions: 0.6.0
Environment: Debian 8.3, Apache Qpid Proton 0.12.2 for drivers and
dependencies, Hardware: 2 CPUs, 15 GB RAM, 60 GB HDD on 2 separate machines
Reporter: Eric Leu
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:
