[dpdk-dev] Still rte_pktmbuf_alloc problems

[Meir Tseitlin <mirots@gmail.com>]

I am modifying l2fwd example to inject additional packets.

I am successfully allocating mbufs with rte_pktmbuf_alloc, but weird
problems started to occur (feels likes concurrency  problems).

I enabled DEBUGs in config file and now my application started crashing on:
PANIC in rte_mbuf_sanity_check:

bad ref cnt

Aborted (core dumped)


Maybe I am allocating mbufs from incorrect core?

But which core should I use? (Other packets are allocated automatically by
PMD)

Thanks
