Hello,

I am using SPDK 20.10 - "Starting SPDK v20.10 git sha1 e5d26ecc2 / DPDK
20.08.0 initialization..."

If I start SPDK NVMe-oF target with 15 cores - "sudo ./build/bin/nvmf_tgt
-m 0x7FFF",
"sudo ./scripts/rpc.py nvmf_create_transport -t TCP" works fine.

If I start SPDK NVMe-oF target with 16 cores - "sudo ./build/bin/nvmf_tgt
-m 0xFFFF",
"sudo ./scripts/rpc.py nvmf_create_transport -t TCP" fails with the
following message

request:
{
  "trtype": "TCP",
  "c2h_success": true,
  "no_wr_batching": false,
  "method": "nvmf_create_transport",
  "req_id": 1
}
Got JSON-RPC error response
response:
{
  "code": -32603,
  "message": "Transport type 'TCP' create failed"
}

Is there any way to use 16 or more cores?

Thanks,
Charlie
