General forum screwed up?

[KFunk]

I can't get into the GD forum, and get this message:

General Error

Could not obtain topic information

DEBUG MODE

SQL Error : 3 Error writing file '/tmp/MYM3MToK' (Errcode: 28)

what up with that? I can't believe nobody else has complained. I even got the same message after logging out and trying on a different computer.

I managed to access all the threads to see my strut bearing thread, but just did it by clicking on the button for the most recent post and clicking 'previous topic' enough times....
