To be honest I have no idea why it worked before. Setting a process to
a certain core takes definitive coding to say "x will have affinity to
CPU y" or using a program like taskset to set the affinity.

I would try the following:
1) man taskset
2) see if taskset works on your system.

Then see if it works. If it doesn't then I would assume that the CPU
or some other hardware in the box is having issues and not allowing
processes on the other cores for some reason.
