I'm working with no cash, 50% of the cores (2), there are two SGS tasks waiting to be executed since yesterday.
Over 200 folders (0-202) in the SLOTS folders all containing primegrid_cllr.exe inside. In the log file I see:
7/10/2017 06:40:02 | PrimeGrid | [error] Can't create task for llrSGS_290507356_0
7/10/2017 06:41:02 | PrimeGrid | [error] exceeded limit of 200 slot directories
Any ideas?

It's not the cache setting that's the problem. It appears that something unusual has happened with your BOINC installation. It's hard to say exactly what the problem is because I've never seen anything exactly like this problem. For some reason, BOINC isn't able to use the slots. I can suggest several steps you can try to fix the problem. I suggest trying them in order, as each step gets more complex. Only proceed if the previous step doesn't fix the problem.

Step 1: Set "No New Work" and let the existing tasks complete, and then reboot your computer. Allow new tasks again. Has this fixed the problem? If not, proceed to step 2.

Step 2: Set "No New Work", let the existing tasks complete, and then detach from PrimeGrid and reboot your computer. Now re-attach to PrimeGrid and allow new tasks again. Has this fixed the problem? If not, proceed to step 3.

Step 3: Set "No New Work", let the existing tasks complete, detach from PrimeGrid, and completely uninstall BOINC. Manually delete the entire BOINC data directory. You may need to open windows explorer "As Administrator" (Windows) or use sudo (Linux) to delete the BOINC data directory because it's possible the problem is that the data directory has the wrong ownership or privileges. Reboot your computer. Install BOINC. Attach to PrimeGrid. Allow new work. If this fixes the problem, great. If not, I'm out of ideas.

I didn't say earlier but there were two BOINC clients running each two SGS tasks and both having the same problem. So I guessed it is something to do with Windows and not BOINC.
So before doing Step 1 as you suggested I did the ultimate Step 0: a reboot and the problem was gone. This will remain a mystery as it is utterly impossible to recreate for testing.

Something may have locked up the slots folder. There are two I can think of off the bat. First, and most likely, is a Virus Scanner. It is best to disable scanning of the BOINC folders. Second, and least likely, is the windows indexing service. During it's scan something may have changed and it went into an unknown state and could not recover.

Excellent points. And you can exclude folders from the indexing service too. I think by default the BOINC folders are excluded but it wouldn't hurt to double check.
