> I deployed one of the PERF clusters using code from trunk with 600 agents.
> Upon trying to add another 600 agents, I was able to register the hosts
> manually through the UI, but the server would get stuck when generating the
> install+start tasks.
> I waited for over 30 mins and it was stuck.
> Refreshing the page caused it go go back to that same step in the wizard, so
> I had to exit the dialog and start those services on my own.
> Because this was the PERF stack, there were no actual bits to install. This
> points to a performance problem on the server.
