Row yielded no match during lookup

I am getting whay seems to be a difficult error to resolve. When running a look up task I am getting "Row yielded no match during lookup" error. I have gone through the data and resolved the following that was suggested on various message boards .

Rebuilt the whole data flow
Ltrim and Rtrim the data
Replaced Null with ''
Checked the data to make sure that case sensitivty is not an issue.

If I run the data today and then run the data a second time in the same day the lookup works fine.

Does anyone know of anything else that could be causing an issue?

Try using "No Cache" and see if that works for you...

Sorry I am using 2005 and not 2008

did you set the lookup to redirect no match entries as no match output in the lookup transform editor?

That is where I am finding the errors. I redirected error rows to a table and all rows are going to the table when I know that there are matches.

could you attach an screenshot from your data flow here?
