It's not a space issue. Other suites ran on that slave after your suite successfully.

I think that the problem is the setting for max semaphores, though I don't know what you're doing to reach that limit.

[dbelenky@ovirt-srv18 ~]$ ipcs -ls

------ Semaphore Limits --------
max number of arrays = 128
max semaphores per array = 250
max semaphores system wide = 32000
max ops per semop call = 32
semaphore max value = 32767

Hi Edi,

Are there any logs? where you're running the suite? may I have a link?

Good morning,

We are running in the OST network suite a test module with Ansible and it started failing during the weekend on "OSError: [Errno 28] No space left on device" when attempting to take a lock in the mutiprocessing python module.

It smells like a slave resource problem, could someone help investigate this?

Thanks,

Edy.
