3 years ago @jodh-intel This looks like a race condition during agent shutdown. Since I know you worked on that area with your work on tracing, do you have any specific insight / debugging trick you could share?

3 years ago When you get a chance @jodh-intel, do you have any tips for debugging? I'm reproducing this locally while trying to fix the segmentation fault in https://github.com/kata-containers/tests/issues/3981

3 years ago @Jakob-Naucke were you running the script as a non-root user locally?

3 years ago @Jakob-Naucke were you running the script as a non-root user locally?
@cmaf I think I did run as non-root, yes. Are you observing more stable behaviour when using root?
cmaf
commented
3 years ago @Jakob-Naucke yeah, I think part of the problem, locally for me at least, is tmux is started as non-root and then expects a password. If you run the whole script as root it will create the other expected processes. If this is the problem in the CI though, it should have been failing prior to this issue.

3 years ago hmm, yeah, it is currently not run in the s390x CI because it's in the CRI_CONTAINERD_K8S_MINIMAL job (which I think doesn't make a ton of sense, cf. , #3990) but we are currently only running the CRI_CONTAINERD_K8S.

2 years ago There was a race condition caused by the way the test checked for a running a VM - I think this may be fixed in https://github.com/kata-containers/tests/pull/4745. I saw it mostly with CLH on Ubuntu and very occasionally with QEMU (both on x86_64).
This is mostly happening on the s390x CI, but I can reproduce this on x86_64 Ubuntu 20.04:
