Rally task hangs in state "Verifying"

I've made some digging on this environment and collect additional info:

Rally process (PID 11852) from `ps aux' output:

develop+ 11852 0.0 0.4 500356 68736 pts/1 S+ Apr13 0:02 /opt/stack/.venv/bin/python /opt/stack/.venv/bin/rally task start --task-args {"controller": 3, "floating_ip_amount": 197, "compute": 44, "vlan_amount": 199, "concurrency": 5, "floating_net": "admin_floating_net", "gre_enabled": false, "current_path": "/opt/stack/rally-scenarios/nova"} /opt/stack/rally-scenarios/nova/boot_and_rebuild_server.yaml --abort-on-sla-failure --tag 11_env_run_rally/114/788afe79

Here we see that process 11852 has opened socket to 172.16.45.102:9292 (Glance service):

(.venv) [root@fuel stack]# netstat -pn --numeric-hosts | grep 11852

tcp 0 0 172.16.44.11:35281 172.18.160.54:5432 ESTABLISHED 11852/python

Here is a Glance service endpoint:
