What does this mean?

It means you session table is full. Are your Scheduled Tasks running? There should be a task that goes through regularly and removes rows from the session table. What do you have your session timeout set to - default is 900 seconds, or 15 minutes.

[OurCouponHome]

Yes, it says 900 seconds.

This is what my scheduled tasks says:

m h D M DoW Title Next Time Controls
56 * * * * Thread Views
This script updates thread views once per hour. This option is suggested for forums with large numbers of threads or users. 09-05-2010

It doesn't look like your scheduled tasks are running. Try running them manually and see if it updates the Next Time column to be sometime in the future. And then make sure you see them actually running. You may want to truncate your session table via phpMyAdmin.

edit: I guess you got your site back. But, looking at the source code, it doesn't look like you are using a default footer template and so the cron job image isn't in there and thus the Scheduled Task is not running. You also have two sets of </body> and </html> tags, which is not proper html. And, you are missing the vBulletin copyright, if you haven't paid for branding free.
