> When using dispatch in a 2-node configuration with a broker between them:
> {noformat}
> 9002 10001 10001 9003
> sender ----> dispatch1 -----> qpid-cpp -----> dispatch2 -----> receiver
> {noformat}
> and initializing in the following order:
> # start dispatch1
> # start dispatch2
> # start qpid-cpp
> # wait for "Link Route Activated" messages on both dispatch nodes
> # stop qpid-cpp
> then the dispatch nodes will core after a random amount of time and after
> sending a random number of

> (info) Connection to localhost:10001 failed: proton:io Connection refused -
