This issue seems to appear every few months in the forum and some people have success fixing it and others perhaps do not.
I am hosted on inmotionhosting.com. I have had to remove wp-cron for now because the file seems to run and run and eat up more and more CPU cycles. I saw where some advice was offered in another post concerning the inability on some hosts for a server to connect back to itself. I sent a message to tech support and was told that the server I am hosted on is able to connect to itself. He writes:
"Your server can connect to itself as we can see users specify localhost in many services all the time.
Now I am at a bit of a loss. I am willing to change hosts if I have to but given that the issue seems to arise from different people I wonder if I would have the same problem there.
Is there any change in the function of wp-cron in 2.8?
Thank you all,
