Anyone has any idea on this?
Can=E2=80=99t believe DPDK doesn=E2=80=99t support such an important feature. This is g=
oing to be a show stopper for real production system.

    Hi dpdk developers,
   =20
    I have a question regarding how DPDK memory module treats memory errors=
.
   =20
    In Linux kernel, it has mechanism (mcelog and EDAC) to monitor the memo=
ry controller and report correctable/uncorrectable memory errors. Using some=
 configurations, if memory errors exceed threshold, system can offline bad m=
emory pages and avoid applications to access/crash.
    Do we have similar mechanism in DPDK?

    Thanks,
