Good morning, The network suite is running Ansible in one of its tests and from the weekend it started failing without a good explanation. It raises "OSError: [Errno 28] No space left on device" when trying to take lock on the python multiprocess module. It smells like a problem on the slave, but I am not sure. Any ideas? Thanks, Edy. =================================== FAILURES =================================== ______________________ test_ovn_provider_create_scenario _______________________ os_client_config = None def test_ovn_provider_create_scenario(os_client_config): network-suite-master/tests/test_ovn_provider.py:68: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ network-suite-master/tests/test_ovn_provider.py:78: in _test_ovn_provider playbook.run() network-suite-master/lib/ansiblelib.py:127: in run self._run_playbook_executor() network-suite-master/lib/ansiblelib.py:138: in _run_playbook_executor pbex = PlaybookExecutor(**self._pbex_args) /usr/lib/python2.7/site-packages/ansible/executor/playbook_executor.py:60: in __init__ self._tqm = TaskQueueManager(inventory=inventory, variable_manager=variable_manager, loader=loader, options=options, passwords=self.passwords) /usr/lib/python2.7/site-packages/ansible/executor/task_queue_manager.py:104: in __init__ self._final_q = multiprocessing.Queue() /usr/lib64/python2.7/multiprocessing/__init__.py:218: in Queue return Queue(maxsize) /usr/lib64/python2.7/multiprocessing/queues.py:63: in __init__ self._rlock = Lock() /usr/lib64/python2.7/multiprocessing/synchronize.py:147: in __init__ SemLock.__init__(self, SEMAPHORE, 1, 1) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ self = <Lock(owner=unknown)>, kind = 1, value = 1, maxvalue = 1 def __init__(self, kind, value, maxvalue): E OSError: [Errno 28] No space left on device /usr/lib64/python2.7/multiprocessing/synchronize.py:75: OSError
