Boinc requests/receives new WUs, but doesn't report finished ones

[SkyeHunter]

I currently experience some weird behavior in Boinc;
On Quadxpc (main cruncher), primegrid functions as expected, but when GPUgrid finishes a WU, it downloads a new WU, but doesn't report the finished one...

How can I make Boinc report & download GPUgrid WU's at the same point in time (when the WU finished) ?

And yesterday exactly the opposite occured; reported but didn't receive new WU's (stood dry for abaout an hour...)

I have the same issues from time to time. Just make sure you have an average WU queue (not too long, so that the WU's can always be calculated but still a significant queue length). I have set mine to 0.5-1 days (PC is 33-50% of time on). I expect such issues to be occurring more in the beginning, when just attached to the project, because only after some time it is able to know how much work can be processed.
Note as well, that GPU computing through Boinc is still in an early stage. Do not worry too much
