Unable to login into the Enforce Console.

When you try to access the enforce console remotely, you are able to login, however after some time you get an RSOD and you are automatically logged out of the enforce. And when you login directly from the Enforce server, it stops on the 'j_security_check' page and you get the error 'An unexpected error has occurred. Contact your system administrator if this problem persists' and then you get a button which says 'Go to login Page'. Once you click on it, then it takes you inside the console.

The Users tablespace is out of space.  Extend the Users tablespace and then reboot the Enforce server.

After the reboot, you will be able to login without any error message.
