Bug ID: 1574
Summary: bnxt dropping all packets when memory is low
Product: DPDK
Version: 23.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: fgiord...@riverbed.com
Target Milestone: ---
Hello,
my DPDK application uses a BCM57412 NetXtreme-E 10Gb RDMA ethernet controller
(bnxt driver). When memory is low (and I reproduce it with a custom binary that
simply allocates memory and uses it) I get a bunch of errors like these in
/var/log/messages:
bnxt_rx_pkt(): mbuf alloc failed with prod=0x10aa
That's probably expected but what happens sometimes is that the NIC starts
dropping **all** incoming packets. Even if I then stop the memory-eating tool,
the application will drop 100% of incoming packets. The only thing to do at
that point is to restart the application.
I tested it with version 21.11.1, 23.11.1 and 23.11.2 and I could reproduce it
on all of them. Is this a known issue? Thanks.
