iphone SDK: too many calls to tableView titleForFooterInSection

Question

Hi, I have a table and I am noticing that for every new row which shows up during scrolling operation basically one call to

tableView cellForRowAtIndexPath

there are 27 (!!!) calls to tableView titleForFooterInSection

Why so many?

While application seems to work fine, I am concern about performance. table has only one section

thanks
