nodes not picking up jobs

OK, I believe I have most of the kinks ironed out of the new farm here…
That being said I am seeing several nodes that wont pickup jobs.
I have verified there are jobs active in the queue with a pool selected that is also assigned to the nodes which arent rendering
I have rebooted the machines in question
I have restarted the slaves on the machines in question.
I have submitted new jobs
No matter what I try there are several machines that just wont grab jobs.

Here is a log from one of the slaves. Its full of entries like this
Scheduler Thread - Seconds before next job scan: 34
Scheduler Thread - Performing house cleaning…
Scheduler - Performing Job scan on Primary Pools with scheduling order Priority, Pool, First-in First-out
Scheduler - Job chooser found no jobs.
Scheduler - Performing Job scan on Secondary Pools with scheduling order Priority, Pool, First-in First-out
Scheduler - Job chooser found no jobs.
Scheduler Thread - Seconds before next job scan: 36

As you can see in this image, some nodes are rendering and others are idle

Thanks so much for any assistance you can provide

I figured it out. its because the nodes didnt have groups assigned to them, just pools.
