[Kernel-packages] [Bug 1788385] Re: vfork in ubuntu_stress_smoke test failed on KVM node with B-KVM kernel
This is not a kernel error; it's a bug in stress-ng when running with the --verify option on systems where memory is low and EAGAIN or ENOMEM occurs. I've fixed this in stress-ng with commit: http://kernel.ubuntu.com/git/cking/stress- ng.git/commit/?id=8ab0ac7ce995517c0cb10db60bee5a19b7b8 Do you mind running a re-test to see if this fixes the issue. Apologies for this stress-ng bug.
