Right. This is the whole point behind the routing queue strategy. It
keeps a user in queue1 from loading up 4k jobs and blocking out users in
other queues. By holding the jobs in the routing queues and trickling
them down into the execution queues, you gain control over what is
presented to maui.
> Or is the 4K limit _per queue_ (following your description it's server-wide) ?
Server-wide, but maui only sees jobs in execution queues.
