@Jamie, is hide_self also applied to this Webmin process? I think we should also exclude it, so not to make users confused.
This is the process that is used to generate the page your seeing. The fact that it’s not running is actually expected, because it’s getting finished right at the moment the page is shown. We just shouldn’t show it at all (by default at least).
It is not a problem! We’ve been trying to explain that you are seeing the process that lists processes. It only runs for a brief moment. Your system happens to be slow enough that it was visible longer than usual and using more CPU than usual. But, there is nothing to solve! I don’t know how else to explain it.
The rest of the discussion between Ilia and Jamie is about whether Webmin ought to hide that process from the list in order to make it so folks who see it (which rarely happens because it indicates a quite slow system, maybe with low memory so it requires swapping memory) don’t panic.
