Nothing, this is a false positive, and you should add it to the exclusion list.

Suspected that. I will add it.

THANKS!!

Is this caused by the long uptime of a mail process?

What do you mean?

I remember having to whitelist quite a few processes that “virtualmin” use, check the root mailbox for any other warnings.
