SmartMonTools: tests get cancelled without any traces

I am testing hard disks with SmartMonTools under Ubuntu 20.04. Tests for some hard disks are not working - they disappear without leaving any warnings or errors.

In short: - Sun Mar 13 16:25:12 2022 UTC: no tests running. - Sun Mar 13 16:26:05 2022 UTC: long test running. - Sun Mar 13 16:26:46 2022 UTC: no tests running, no test results recorded. How can I find out **why those tests get cancelled - any logs available**???
