The binary crashes in the virtual test. Maybe capabilities are missing but I did not have time yet to look at it more closely. |

Thanks for the feedback. I suspect the failure is caused by the mlockall() and affinity-related changes in this PR. In the current test environment, these calls may be missing the required permissions/capabilities, which can lead to a crash instead of a clean fallback. I will revise the PR and run additional local tests to make sure the program handles such environments more safely and does not crash when these features are unavailable. |
