Well, it has space at the time the 'df' command was issued; but it
may have run out of space during an operation, and as part of
operation recovery, the operation may have removed the partial work
from /tmp.

I would check the AIX Error Log, where AIX usually creates an entry
(e.g., JFS_FS_FULL) when a file system has filled. Also try the
bosboot -q option.
