Multi Sites required constant reauth


I have some multi site websites setup, where when you in the backend editing posts and menus, the site keeps kicking you out and making you reauth your account.

They are running domain mapping + pro sites + easy blogging.

The url it sends you to is:

http:// // wp-login.php?redirect_to=http%3A%2F%2F %2Fwp-admin%2F%3Fwdeb_off&reauth=1

Any ideas on where to start? it is becoming unworkable as I cannot even edit my wordpress menu.
