Hi,

You can refer section 20.3 [Multi-Process Limitations] in DPDK Programmer's
Guide.

It says,

• The multi-process feature requires that the exact same hugepage memory
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.

Thanks
Venkat
