I just worked on this tonight myself. When doing > 1 primary (for 
example pktgen and app), I had to specify:

--no-shconf
--file-prefix pktgen
--file-prefix app

Or you get a panic and RTE fails to init, but the file-prefix seems to 
get applied both to the hugepage mmap() files and also to the lockfiles 
in /var/run:

$ ls -a /var/run | egrep -i '^\.'
.
..
.pktgen_hugepage_info
.rte_config
.rte_hugepage_info
.sdn_sensor_hugepage_info

So I think you have to keep the different primary-secondary sets 
separate using --file-prefix .

Matthew.
