I'm using CX5-LX device and have not seen any issues with it.
Would it be possible to retest with kmemleak?
Here is the device I used.
Network controller: Mellanox Technologies MT27500 Family [ConnectX-3]
The issue always can be reproduced with about 1000 time.
Another thing is I found one strange phenomenon from the log:
before the OOM occurred, most of the log are about "adding queue", and
after the OOM occurred, most of the log are about "nvmet_rdma: freeing
queue".
seems the release work: "schedule_work(&queue->release_work);" not
executed timely, not sure whether the OOM is caused by this reason.
Here is the log before/after OOM
