Joomla Admin Hit Again and Again for Logging In

Even though I have the login reset set to over 30 minutes, Im having a log in problem with Joomla. It seems every few minutes I have to re-log in as the admin. Something must be wrong since each time it happens, the # of people logged in “increments” - like its treating each re-log in I make as a new session with a new user. Anyone know whats going on?
