What is the curl error 52 “empty reply from server”?

Question

I have a cron job setup on one server to run a backup script in PHP that is hosted on another server.

The command I\'ve been using is

curl -sS http://w

In my case this was caused by a PHP APC problem. First place to look would be the Apache error logs (if you are using Apache).

Hope this helps somebody.
