Strange error log message from


I was going through the error logs when I spotted a post request that happens everyday from a dreamhost server, it seems to try and activate a wordpress cron job, has anyone else seen this? Why would a dreamhost webserver make this type of request? - - [20/Aug/2012:01:32:03 -0700] “POST /wp-cron.php?doing_wp_cron=1345451523.1074879169464111328125 HTTP/1.0” 200 248 “-” "WordPress/3.4.1;" - - [21/Aug/2012:00:26:03 -0700] “POST /wp-cron.php?doing_wp_cron=1345533963.4923720359802246093750 HTTP/1.0” 200 248 “-” "WordPress/3.4.1;" - - [20/Aug/2012:03:30:14 -0700] “POST /wp-cron.php?doing_wp_cron=1345458614.7253448963165283203125 HTTP/1.0” 200 248 “-” “WordPress/3.4.1;”
After doing more research I see that seeing many wp-cron.php requests is normal with each wordpress request but still not sure why it shows up as an error rather than in the access log.
