a similar issue https://github.com/giampaolo/psutil/issues/1765

And https://github.com/giampaolo/psutil/issues/1826

It seems that psutils doesn't have full features on Macos.

I received this once on Linux.Python 3.9.5 (default, Nov 23 2021, 15:27:38) . It originated from the _logger.debug line below.

```

for p in psutil.process_iter(attrs=('pid', 'ppid', 'exe', 'cmdline')): if 'ssh' == p.name(): _logger.debug(f"{p.pid} {p.ppid()} {p.exe()} {p.cmdline()}")

I unfortunately not have resources to test on more than recent stable Ubuntu. PRs are always welcome.

I'm closing this for now.
