A failed run leaves behind a zombie server container: docker_stop_srv cats the log before docker stop, and when the log is missing the cat aborts the script (set -e) before the stop runs. Being a detached container, the zombie survives the build and keeps the MAD agent registration on the HCA, so every following build's server fails with EINVAL and the client hangs until the job timeout - the stage breaks for all PRs until the zombie is removed by hand. Stop the container first and sweep zombie ucx_perftest_* containers before starting a new server, so one bad run cannot wedge the stage.

What?
Stop the MAD perftest server container reliably, and clear any zombie
ucx_perftest_*container before starting a new one.Why?
On a failed run,
docker_stop_srvrunscaton a missing log, which aborts underset -ebeforedocker stop. The detached server survives as a zombie and holds the MAD registration on the HCA, so every later build's server dies withmad_register_server_via ... Invalid argumentand the client hangs until timeout. Broke all PRs until zombies were cleared by hand (e.g. build 127843).How?
docker_stop_srv:docker stopbeforecat.docker_run_srv:docker rm -fsweep ofucx_perftest_*to heal zombies from a canceled or crashed prior run.
