No.

For this specific trace below, you are probably trying to attach a
secondary process to a primary process (which was OVS iiuc) which does
not have the same enabled DPDK libraries/drivers.
Having the same dpdk components (from the same version) in both
binaries is the only way for multiprocess to work: I'd recommend
linking both your binaries against a built once and for all set of
dpdk libraries.

Besides, please note that the OVS does not support multiprocess.
Issues had been reported in the past (like pdump secondary process
crashing OVS).
There is work atm in OVS that will make multiprocess disabled.
