Upload of file failed
 

I have 4 forums running on one server. In the last few days, suddenly no one can upload avatars or photos.

The day it started, All of the boards went down and I got the error: Can't create/write to file '/tmp/#sql_67fa_0.MYI' (Errcode: 122)

My server admin believed it looked like the 'tmpdir' variable in MySQL needed to be changed to reflect this directory and made that change.

Now, no one can upload avatars or ad photos to any threads. I've tried moving attachements out of the database and turning off safemode and adding them back to the database, but still same problem. Any suggestions?
