Secondary process crash in rte_eal_init

Secondary process crash in rte_eal_init

[Dey, Souvik]

Hi All,
                We have a single primary application with multiple secondary applications launched on the same cpu core. When the system boots up for the first time ,the primary comes up followed by the secondary process everything works fine. But in between if I try to restart the secondary processes without restart the primary, the secondary process crashes with the below stack trace. Any idea what is going wrong out here.

============================================
Stack Trace of the Crash :
(gdb) bt
#0 0x00007f4dad6e01b5 in raise () from /lib/libc.so.6
#1 0x00007f4dad6e2fc0 in abort () from /lib/libc.so.6
#2 0x0000000000402545 in __rte_panic ()
#3 0x00000000007353f4 in rte_eal_init ()
#4 0x0000000000403133 in main (argc=10, argv=0x7fff2c52fea8)
============================================

Hi Dey,

Could you try to reproduce the issue with one of the multi-process 
examples from DPDK?
Also you could provide some info such as command line options when 
running both primary/secondary apps, dpdk version, etc...
