When I connect an SPDK initiator it will try to connect using 1024 connections.
The linux target is unable to handle this situation and return an error.

Aug 28 14:22:56 crashme kernel: [169366.627010] infiniband mlx5_0: create_qp:2789:(pid 33755): Create QP type 2 failed

Aug 28 14:22:56 crashme kernel: [169366.628498] nvmet_rdma: nvmet_rdma_alloc_queue: creating RDMA queue failed (-12).

Seems that the target is trying to open a queue-pair that is larger than
supported, which device are you using?
