michael goulish closed DISPATCH-2173. ------------------------------------- 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... > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
