I'm sending iOS Push Notifications in the Enhanced Notification Format using PHP.

When I send the same message to the same device >= 600 times in a single connection, it sometimes fails at the 600th time with a status code 8 error (Invalid Token). The token is obviously valid since I'm receiving the notifications on a real device.

This happens on both the sandbox and production server.

What could be the cause of this? Is there a rate limit?
