http://wp-admin/edit.php

I have been running into this when I am saving or updating settings on my wordpress installation. Where I will be rocking and rolling updating pages etc, then when I hit save/update, it will loose the domain and will 404 error. The address bar will then read:

http://wp-admin/edit.php vice http://url.com/wp-amin/edit.php

If I simple go to the address bar and type in the url.com it saves and works again.

Any ideas?

I am on a mosso server, which has hindered some things in the past, but I wanted to check here first.
