I checked out v36.0 of rdma-core and rebuilt that. rdma is version 5.9.0 but I doubt that will have any effect. My startup script is export LD_LIBRARY_PATH=/home/bob/src/rdma-core/build/lib/:/usr/local/lib:/usr/lib sudo ip link set dev enp0s3 mtu 8500 sudo ip addr add dev enp0s3 fe80::0a00:27ff:fe94:8a69/64 sudo rdma link add rxe0 type rxe netdev enp0s3 I am running on a Virtualbox VM instance of Ubuntu 21.04 with 20 cores and 8GB of RAM. The test looks like sudo ./check -q srp/001 srp/001 (Create and remove LUNs) [passed] runtime 1.174s ... 1.236s There were no issues. Any guesses what else to look at? Thanks, Bob
