--- Comment #14 from Vipin Varghese (vipin.varghese at intel.com) ---
Hi Hideyuki,

note: the Bugzilla is raised for the current documentation available
`https://doc.dpdk.org/spp/setup/getting_started.html?highlight=aslr`.

as per the documentation

```
SPP is a DPDK multi-process application and there are a number of limitations .

Address-Space Layout Randomization (ASLR) is a security feature for memory
protection, but may cause a failure of memory mapping while starting
multi-process application as discussed in dpdk-dev .

ASLR can be disabled by assigning kernel.randomize_va_space to 0, or be enabled
by assigning it to 2.
```

Q&A:

Thanks for your answer.
[VV] I have asked a question, is ASLR to be enabled or disabled.


SPP20.02 only supports using DPDK20.02. This idea is from first release of SPP
and we are not planning to change it without special reasons.
[VV] From this statement your recommendation is to disable the same.

Why have you shared `2. with `Using DPDK20.02 with ASLR enabled, Segmentaion
fault takes place.`, but the recommendation from SPP team is to disable.`

I am changing the priority to high and critical, waiting for the update from
SPP team.
