I'm running wp-cron.php via:
wget -O - -q "http://milwaukeeconsumer.com/wp-cron.php"
every 8 minutes, and every hour at :32 after the hour, I get an email with "Connection closed" as the body of the message. It does not happen at any other time, even though it's running every 8 minutes.
I previously was running it every 5 minutes, and at that time, I was getting connection closed at :30 after every hour.
I checked with my VPS provider, and they don't know of anything that could be giving the server trouble at the bottom of every hour...
Any ideas? Is this related to wget not being able to connect to the webserver? or is it related to php not being able to connect to the database? I just don't know what to look for.
