I see some comments here: https://mails.dpdk.org/archives/users/2017-August/002335.html About how that parameter can only be used with ASLR off. This thread seems to confirm that you can just keep restarting with a value that works: https://mails.dpdk.org/archives/users/2017-June/002049.html It would be nice to avoid that if possible. This patch also says the secondary process value shouldn't be used: https://patches.dpdk.org/patch/41232/ My question is, if I can turn ASLR off, are there guidelines I should follow on how to set that value reliably on the primary? Do the secondaries really not need it?
