Problems With cURL

Ok, our server has been running flawlessly for the last 144 days as everything has been running smoothly, and hasn't needed a reboot. Now for some reason, cURL when executed by our billing script is taking 90-98% of the servers resources. Nothing was changed on the server except for an upgrade in php from version from 4.1.0 to 4.1.2.
Does anyone know what might wrong with the server, because we cannot take on new clients anymore due to this problem?
