Dear,
I'm the new for using DPDK.
I met the problem while trying to use pdump to capture the packet from my
own application, but it bumps into some error as below. Do you have any
suggestions?
[oai@localhost pdump]$ sudo ./dpdk-pdump -- --pdump
'port=0,queue=*,tx-dev=/tmp/tx.pcap,rx-dev=/tmp/rx.pcap' EAL: Detected 72
lcore(s) EAL: Detected 2 NUMA nodes EAL: Multi-process socket

[./dpdk-pdump(main+0x52e) [0x480f1e]] 1: [./dpdk-pdump(__rte_panic+0xe0)
[0xe0f600]] Aborted
P.S.
The DPDK version in our lab is for 19.11.
After modifying CONFIG_RTE_LIBRTE_PMD_PCAP=y & CONFIG_RTE_LIBRTE_PDUMP=y,I
try to use ICC for the compilation.
Also, I already add function rte_pdump_init() in my application.
Best Regards,
Shu-hua, Liao

Your mailer is mangling that message. But it look like the secondary
process failed to start at all.
Is the application and pdump running in same environment?
For example is the application running in a container where the namespace
is different?

Did you check return value from rte_pdump_init()?
It might be helpful to see the full DPDK config.
