Premature end of script

I’m getting tonns of this errors in my error log:
[Fri Aug 12 02:18:02 2005] [error] [client xxx.xxx.xxx.xxx] Premature end of script headers: /dh/cgi-system/php.cgi

I’m running a Drupal site. I’m ready to pay for a programmer, who can find the bug for me. Please let me know!

Do you guys know anyone I can hire to find the bug on this issue?
