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

Target Milestone	---

The multi-process example applicat=
ion 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 an=
d a
client application will fail on startup. The Linux =E2=80=9Caddress-space l=
ayout
randomization=E2=80=9D security feature can sometimes cause this to occur.

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

Resolution/Workaround:
See the =E2=80=9CMulti-process Limitations=E2=80=9D section in the DPDK Pro=
grammer=E2=80=99s Guide for
more information.

Affected Environment/Platform:
All.

Driver/Module:
Multi-process example application
