Added some more smarts to make this a non-failure issue, just a resource limiting exit on each stressor: http://kernel.ubuntu.com/git/cking/stress- ng.git/commit/?id=d3db4119cdd3bee439a4f2a6cc36d27ff3ce6c4b -- You received this bug notification because you are a member of Ubuntu Bugs, which is s

NOTE: I'll fix up stress-ng to detect this and report it is a problem, but I do think the failure is correct - stress-ng hit an upper resource bound set by the system and failed. However, it should be reporting that the errno meant that there were no resources left. -- You received this bug notif

OK, I can see one big problem, the timeout command is being used to SIGKILL stress-ng - that means all the child processes get SIGKILL'd and hence abort without cleaning up. One ends up with a file system full of garbage files which will cause subsequent tests to break. I suggest: 1. Sending SIG
