What DPDK version is this?
In any case, i don't think there are specific circumstances in which
this is likely or unlikely to happen. Anything could be occupying those
addresses - libraries, code, more libraries, more code... The address is
taken, and EAL reports it. If you're not going to use secondary
processes, it can be ignored. If you are, well, truth is there's little
you can do to fix it :( This is just a byproduct of how our secondary
processes work.
