            Bug ID: 1628
           Summary: Multi-process sample app requires exact memory mapping
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: examples
          Assignee: dev@dpdk.org
          Reporter: nandinipersad361@gmail.com
  Target Milestone: ---

The multi-process example application assumes that it is possible to map the
hugepage memory to the same virtual addresses in client and server
applications. Occasionally, very rarely with 64-bit, this does not occur and a
client application will fail on startup. The Linux “address-space layout
randomization” security feature can sometimes cause this to occur.

Implication:
A multi-process client application fails to initialize.

Resolution/Workaround:
See the “Multi-process Limitations” section in the DPDK Programmer’s Guide for
more information.

Affected Environment/Platform:
All.

Driver/Module:
Multi-process example application
