Hi Andrey,

I've never seen that issue on any of the Xeon platforms I've tested with.  Not sure about Epyc though.

I can't figure out where "set_mempolicy failed" gets printed by DPDK though.  I see where DPDK prints messages when set_mempolicy fails, but it's in a different format.  Do you by chance have any local edits in your DPDK submodule?

    Hi guys,
    
    I'm running 20.01 (default configuration) on a CentOS 7 Epyc-based
    system, and getting a lot of subj warnings like in the below example.
    Does that point to a system configuration issue that needs to be
    fixed?
    
    Thanks,
    Andrey
