Tramp is a library, and it isn't activated on its own. So let's see why
it is called:

Well, `desktop-auto-save' is in progress, and it calls Tramp functions
again and again. You should suppress this when the remote connection
isn't available.

What are your values of `desktop-buffers-not-to-save',
`desktop-files-not-to-save' and `desktop-modes-not-to-save'?
