My latest Theory show that they are using 0.385 of a core.
For a while, I was running 2 of them per core on a 16 core Ryzen 2700, but this has straightened out now.

Is this a bug or a feature?

Boinc probably get wrong value from config to theory and new wrapper could start if several are stated with lower value then full core.
I have experience before that theory had low usage it started a new task. Happen a few times when theory was mt task, But not seen that got that value in boinc manager. It could possibly be able to continue but could break in long run.

A restart of boinc service could change state but as run native that is not good.

Task would start a single pid and add up more to until it feed core it could be several process pending or stalled or python script is busy. You could probably monitor task running or check pstree or possibly get something in runrivet.log

Could probably be both.

Thanks. I just got 13 of them all together in a bunch, but now they are back to normal.
So it must have been a startup problem, as I had recently attached the machine.

Now two with 0.5 Cpu are running well - one is a sherpa 2.2.4.
Only problem is output.tgz is not deleted in the slot-folder after finishing and uploading.
Boinc 7.16.6 from CentOS 7.7 (CentOS Linux 7 (Core) [3.10.0-1127.19.1.el7.x86_64|libc 2.17 (GNU libc)].
WCG is cleaning the slot-folder correct!
