No idea about this one. Moreover, I cannot reproduce this with 17.4
freshly built from sources. I would suggest that you try to build a
"standard" PLT (e.g. dialyzer --build_plt --apps erts kernel stdlib) or
something of that sort, and watch what's happening using htop (or similar).
If that one does not show multicore activity, then something is wrong
with your installation. Try to build and install an OTP from sources
then. In any case, write a follow up mail here to see if that was a
false alarm or the problem persists.
