Anyone else having issues getting CPU WUs assigned? The GPUs I fired up today seem to be folding fine, as are my low-thread machines. But my 2 big thread CPU clients are failing to pull down WUs with this error:
05:50:50:WARNING:WU00:FS00:Failed to get assignment from '171.67.108.45:8080': Empty work server assignment
05:50:50:WU00:FS00:Connecting to 171.64.65.35:80
05:50:51:WARNING:WU00:FS00:Failed to get assignment from '171.64.65.35:80': Empty work server assignment
05:50:51:ERROR:WU00:FS00:Exception: Could not get an assignment
I launched the FAH client for the first time on my old home rig (an i7-3770K) about 24hrs ago and it has been looping that error the whole time. I've rebooted Windows and restarted the client several times. I pulled up the NaCl client but the PPD is pretty pitiful - I'm assuming at least partly due to the lack of bonuses on NaCl.
I'd gotten my new workstation (i7-6900K) folding over the weekend and it was doing fine, but when I added my HD 7870 and adjusted the number of threads going to the CPU it killed the WU I was working on, and now that client won't pull down any more CPU WUs either (same error as above). I went ahead and launched NaCl there as well, but I'm at ~15K PPD instead of ~75k PPD.
Interestingly enough, I've got an old i5-650 that I threw my HD 7950 into - I set it up from the get-go to have 2 CPU threads folding and 1 GPU slot. That's been folding to both the CPU and GPU slots perfectly - although I don't think either slot has turned in a WU yet.
Environment Variables:
The i7-6900K and i5-650 are on the same network at my office. The i7-3770K is at home. All are running Win10 x64 and they should be pretty well up to date.
I've considered reinstalling the FAH client on the misbehaving machines, but at least on the 6900K I'll wait until the GPU WU has finished.
Suggestions? Thanks

Try this - so that I can try and help you debug it (because I have a feeling that you're encountering the same or a very similiar problem that I ran into when I fired up my systems).
On all of the systems, can you list your CPU, your GPU (if/where appliable), how many cores your CPU has, and how many threads your CPUs are using for Folding?
(for the last one, you can click on the Folding@Home tray icon, and then click on Advanced Control" and under cpu, there should be a number (like "cpu: 5") and that will tell you the number of threads that it is running.)
I ran into the same problem yesterday and after doing a little bit of research on the Folding@Home forums, apparently, there is an issue with WU assignment if the number of threads is a prime number like 7, 11, 13, etc. (and also 5, as I experienced/encountered yesterday), which presents an interesting dilemma/pickle.
If you have a CPU and GPU, GPU takes up a thread so CPU is now (numcores-1) threads (i.e. if you have a 6 physical core processor, it will run with 5 threads and one GPU), which has problems with WU assignment.
So your choices are to either go down to 4 threads, which means you have an idle core not doing anything, or for it to go up to 6 threads, which now you might have conflict between the CPU FAHCore and the GPU FAHCore (conflict for resources to feed the GPU).
(That's also if you have HyperThreading Technology disabled in the BIOS.)
If you have a 6-core processor with HTT enabled, then you might be able to force it to run with 10 threads so that all 5 physical cores will be fully loaded.
Give that a shot. See that helps you out in terms of you getting more WUs assigned to your systems.
