AMFPHP Remoting from Flashcom

[nitrofly]

I have a FlashCom app that makes a service call when a user connects (to authenticate the user against MySql db). I am encountering a problem where *only every second connection receives a result handler from the service.

To eliminate coding errors on my part (still being new to AMFPHP) I deployed a great login tutorial by Jorge Solis to my server and the problem persists.

You can see his demo working as it should here:

user: test
password: test

...and my deployment of his demo on my server where only every second connection works here:

Anyone seen this kind of battyness before and know what causes it?
