[wp-hackers] Wordpress 2.0 trackback issues

The problem is not with execute-pings.php. The problem lies in the 
function that calls this script. If you have a row in your 
wp_posts-table where "to_ping" has some faulty data in it, the function 
hangs in an endless loop and never executes the trackback (calling 
execute-pings.php) ... you can see this in your webservers logfile.
