-------------------------------------
Resolution: Won't Fix
It has been pointed out to me that a 30-mesh is not very realistic.
I was forced to admit that this was probably true.
> 30-Mesh Behaving Badly
> ----------------------
>
> Key: DISPATCH-2173
> URL: https://issues.apache.org/jira/browse/DISPATCH-2173
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Reporter: michael goulish
> Assignee: michael goulish
> Priority: Major
>
> While testing scale-up of full-mesh networks I encountered some Bad Behavior
> at 30 nodes. (435 connections.)
> On my first try, 15 of the routers died.
> On my second try, no nodes died – but the network never converged. It
> consumed all available CPU (32 cores) for three minutes, and the 30 routers
> printed a combined total of more than 1000 radius calculations to their logs
> by the time I became wrathful and cast them all into the Bitbucket of Woe.
>
> For reference, those radius calculations are how I decide that the network
> has converged – everybody has settled down and agreed on the topology and
> stopped talking about it. The last thing each router prints to its log is a
> radius calculation, and then it's done. This may happen multiple times for
> each router, but when the total number of such prints stops changing – the
> network has converged.
>
> For 15 or 20 routers, the number of such prints was 20 or 40 or so. When this
> test exceeded that by 25x, I decided it was never going to quit.
>
> ...Now looking at the logs to see if I can figure out what was happening...
