>>Dear Reshma,

>>Thanks for your kind response ! Unfortunately, it still can't work.

Also, could you please paste me the lbpcap-devel package version on your system.

Few options you can double check
1)Make sure your primary application is calling rte_pdump_init()/ret_pudmp_uninit() to initialize/uninitialize the pdump library.
2)If you are using a shared library build,   double check you are  linking pcap pmd properly in primary build as explained in below link
3)If you are passing any pci device using  eal "-w" option to primary,  try to pass the same device to secondary also using "-w" option .

If you still see the issue please paste the full primary and secondary application run log with command that you are running.
Also what kind of build you are using.
