> I am running a three node fully connected mesh of dispatch routers with 10000
> attached clients and I am seeing some unstable inter-router connections (I am
> sending around 1000 small, less than 1K, messages per second through the
> network). The inter-router connections fail every so many seconds with the
> message:
> {{Connection to router-2:55672 failed: amqp:session:invalid-field sequencing
> error, expected delivery-id 7, got 6}}
> (the numbers 7 and 6 differ per connection loss)
> In wireshark, using the attached tcpdump capture, I can see that every time
> before the inter router connection is dropped, therw is a rejected
> disposition with the message:
> {{Condition: qd:forbidden}}
> {{Description: Deliveries to a multicast address must be pre-settled}}
> The routers are connected as follows:
> * router-0 -> router-1
> * router-0 -> router-2
> * router-1 -> router-2
> The routers are running as a docker container (debian stretch) on google
> compute engine machines (every router on a separate node).
> Attached are:
> * my qdrouter.conf (from one of the routers)
> * a log snippet from router-0 at debug level from connection drop to
> connection re-established to connection drop again.
> * a tcpdump capture of the inter-router connection between router-0 and
> router-1 during which several of the failures occur
> Versions:
> * [email protected]
> * [email protected]
>
> [^qdrouterd.log]
> [^qdrouterd.conf]
> [^router.dump]
