"waiting to start"

What would cause slaves just to sit at “waiting to start”

i cant’ see to find what’s limiting the amount of slaves

they’re not blacklisted, number of machines that can render this job concurrently is 0, no dependencies, not on bad slaves list not scheduling

here’s a screenshot

When i turn the pulse off everything seems to render but my throttling settings shouldn’t have caused that no?

I’m told it definitely be due to throttling. Or it can be that it’s taking forever to start the render process, but that’s unlikely for the Monitor.

Can you try disable throttling and see what change it has?
