That looks a little odd. Can you check a couple things - just stuff that may be detective work.

Check that session file it was opening/closing

Is it still there and how big is it? If it's gone then it may have been that is was caused to grow too big and then released after it consumed all space. No idea why that would be though. Are there other sess_* files there and are they big?

Check your /var/logs to see if any of your logs have grown huge. That can happen and cause trouble.

It looks like your /var directory is mounted normally in / - so it's use should show up there in df output. Perhaps something went wrong and caused massive space allocation and upon closing that space was released.

Also look in your /tmp directory and see if anything big is happening there.

Just ideas that I think I would look at if I saw this.
