It looks like it is possible for the separate started wpa_supplicant process to remain running after a test case like fst_sta_config_default. This would result in failures to run any following test case that uses the wlan5 interface. Try to kill the process more thoroughly by waiting for the PID file to show up and write more details into the logs to make it easier to debug issues in this area.
