Cron Errors in Apache Logs

We’re getting a lot of errors in our Apache logs due to the WordPress cron. And by a lot, I mean multiple log entries per second. I edited /wp-includes/cron.php to prevent it from calling the wp-cron.php for now. Does anybody know what’s wrong?

Here’s what the access_log entries look like:
127.0.0.1 – – [19/Feb/2008:00:05:35 -0600] “GET /wp-cron.php?check=f3394916db41113efaf8fe624655183a HTTP/1.0” 404 292 “-” “-“

And here’s what the error_log entries look like:
[Tue Feb 19 00:05:35 2008] [error] [client 127.0.0.1] script ‘/var/www/html/wp-cron.php’ not found or unable to stat
