Yesterday I updated to new release 7.4.27 and now I can no longer download GPU tasks from Milkyway. I can download GPU tasks from other projects. I get the following error:

Milkyway@Home | Not requesting tasks: don't need (CPU: job cache full; NVIDIA GPU: job cache full)

There were NO GPU tasks running at the time. The system has total 8 cores with HT turned on and a GPU. It is set to run 75% CPU (6 cores), so there was cores open and no GPU tasks running. As soon as I allowed a different project to ask for GPU work it received it without issue. This problem did not occur on the previous 7.2.42 version.

So MW must be doing some odd check when work is requested that thinks I am overbooked and cannot do the work.

Found the issue. If you set a project to 0 priority it will not download work anymore if there are other projects with a larger priority and even if those projects do not have any work. Same with CPU.

** Solved **
Known bug on this version.
