MAC Error message on starting FMP Server

[anothersmurf]

When FileMaker Server starts up (when the computer boots), I get an error message sent to me by email from FileMaker Server:

Error 92 [servername] Could not complete operation on database "Databases" because it is not currently open.

I do not have a database called Databases, and all of my hosted databases are in a folder called "hosted", in a custom location. I think the server might be somehow mistaking the default "Databases" folder, which I don't use, for a database? But if that is the problem, I don't know what to do to fix it.

Everything otherwise works fine, all my databases open up and people can access them as expected.

Could someone tell me what the error message means and what I can do to fix the problem?

Thank you.
