Thanks for the feedback ! I just wanted to run some more extensive tests in a real environment to make sure there are no regressions. I'll look into adding the coredump tests ASAP! |

I have fetched the coredumps, uploaded it to the S3 storage and retriggered tests. Will you mark the PR as ready for review? |
