It says, =E2=80=A2 The multi-process feature requires that the exact same hugepage m= emory mappings be present in all applications. The Linux security feature - Address-Space Layout Randomization (ASLR) can interfere with this mapping, so it may be necessary to disable this feature in order to reliably run multi-process applications.
