PayPal Instant Payment Notification (IPN) Warning

Let me know if any of this helps

* Upgrade to 1.7.2 (some PayPal Standard related fixes here)
* Make sure that *ipnhandler* is ignored by your caching plugins, etc.
* Google Page Speed has been causing issues with this. If you are using it, stop using it and try another caching/etc solution (W3 Total Cache is good) that you can exclude files with.
* If you are on lower tiered shared hosting, upgrade to a VPS or higher plan. The ipnhandler calls can sometimes timeout.
* Consider switching to PayPal Express.
