sitemap generate warnings

[lars_hoej]

Hi

I keep getting this sitemap warning each day the sitemap is generated, but I simply cannot find out what the problem is: 

Sitemap generate warnings:

Cannot send headers; headers already sent in /var/www/vvspower.dk/public_html/app/code/local/Mage/Epay/Model/Observer.php, line 44

And where to look for it... 

Can anybody please help?
