5775 PrimeGrid 1/23/2018 10:28:59 AM Not requesting tasks: don't need (CPU: job cache full; NVIDIA GPU: )

I have seen this on a number of occassions, it eventually fixes itself, but when it does show up forceing an update still results in the message that the NVIDIA queue is full when it isnt.

This system has 2 identical gpus, both gtx670, and in addition I set cc_config to allow multiple gpus.

This problem can be solved by waiting out the remaining PrimeGrid work unit. When it completes the following shows up

JYS-EVGA-670

look at 5783 to 5788: that one task completed and then I got two more. Seems ok
look at 5792 to 5793: One of the PrimeGrid completed pretty fast but it thinks the NVIDIA queue is full so that GPU is now empty! Could it be checking if the queue is full before releasing the finished work unit?

It will continue running that single task until it completes and then download another 2
I had suspended all other tasks on the core 2 quad system to ensure the cores were all available.
Not sure if it matters, but 3 einstein nvidia tasks had completed about an hour earlier but due to project maintenance they could not be uploaded. I dont think this caused this problem but I thought I would mention it. I am also excluding all other PrimeGrid tasks using cc_config. Don't think this matters though. Boinc (v)7.8.3
