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 ena= bled 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. --=20 You are receiving this mail because: You are on the CC list for the bug.=
