DPDK 18.11.2 and 19.02 crashes on ConnectX-4 under a significant load
(e.g., 50Gbps). It crashes in rxq_cq_decompress_v(),
in rxq_burst_v(), in mlx5_rx_burst_vec().
Any help is appreciated.

Hi Yasuhiro,
Have you tried disabling rx cqe compression?
rxq_cqe_comp_en enables optimized received packets’ completion algorithm when PCI back pressure is detected. To disable this please set to 0 (“rxq_cqe_comp_en=0”).

Chen
Thank you Chen,
It seems that disabling rxq_cqe_comp_en is not easy for me.
I’m writing my own DPDK app and I couldn’t find proper DPDK functions
to set devargs. I’ll try to disable it, checking references from test-pmd.
(and I haven’t reproduced the bug neither in test-pmd nor l3fwd…)
I filed a bugzilla.
