Don't worry about that: it's just that the previous error message has been
output before DW has tried to send its HTTP headers. That'll be fixed
once you fix the other problem.

In that case, it might be that the temp dir is on a filesystem that is
nearly full. When it gets too full, PHP can't write to it, but then it
gets cleared out (a bit) by some other process, and then you can write to
it.
I'd check that out first, just to make sure there's space (try the df
command). Of course, also check the permissions on that temp dir, but if
it's working sometimes then they're probably okay.
