I've tried some stress testing. It is definitely not hard to produce *some* crashes/hang-ups. However, I'm not sure whether these tests are very meaningful to tackle the problems we see under actual production load. You can read my comments around https://progress.opensuse.org/issues/114565#note-73 for more details. We could also still give you access to the machine (ipmi and ssh) if you want to run some tests for yourself. (If you have better ideas for stress testing that would also already be helpful.)
