           Version: 18.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED

         Component: core
          Assignee: dev@dpdk.org

  Target Milestone: ---

I am trying to allocate 32Gb memory via rte_calloc applying config changes
advised in https://bugs.dpdk.org/show_bug.cgi?id=3D608. I am using 1Gb huge=
pages.
However, in order to success, the system requires to reserve 66 pages which=
 is
too much - we just don't have enough RAM on our production hosts.

Please advise.
