Help! Live shop suddenly getting session errors

My OSc 2.2 shop has been live for about 1.5 years. Suddenly today, I began getting these errors both on the admin side and catalog side:

My shop is mostly stock, but I do have SEO URLS and a few other contributions installed. Does anyone know what caused these errors?
thanks in advance.

Not sure but I would check sessions settings in admin panel configuration and also clear cache as well

The error message tells you exactly what the problem is: /tmp is full. You need to free up some space.

That is what this means:

failed: No space left on device

Yep your "space" is full. Clean up your files, move emails off the server, remove other files not used/needed.

OR Check your host plan that your on. MOVE or UPGRADE to get more space.

Folks,
Thanks for the replies. I called my Host first thing today, and they resolved the issue right away.
