I have noticed a WU that is running now since 14 hours on my R9-3950X. All other WUs were finished in about 1 hour
This long running WU is also using only 8 Threads of the CPU - but it is stated as 32x.
The result is that the CPU is running hot (4 cores in full power) and idle at the same time.

Is this behaviour expected or is it a bug?

I got another WU like this on another PC and could watch it live during calculation.
It started with all 16 threads, at around 50% there were only 12 cores active, now at 93% it is decreased to 9 cores.
At the end it might be just 1 core?
