AMFPHP + PHP 5.3.1

I don’t get PHP 5.3.1 working with amfphp 1.9.

I always got the following error:
(mx.rpc::Fault)#0
errorID = 0
faultCode = “Client.Error.MessageSend”
faultDetail = “Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed”
faultString = “Send failed”
message = “faultCode:Client.Error.MessageSend faultString:’Send failed’ faultDetail:’Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed’”
name = “Error”
rootCause = (Object)#1
code = “NetConnection.Call.Failed”
description = “HTTP: Failed”
details = “http://localhost/amfphp/gateway.php”
level = “error”

I don’t know what happens. And when I look into the apache error.log, I got:
[Mon Mar 22 20:53:05 2010] [error] [client 127.0.0.1] File does not exist: D:/Program Files/Apache/htdocs/amfphp/browser/history.htm, referer:http://localhost/amfphp/browser/
[Mon Mar 22 20:53:05 2010] [error] [client 127.0.0.1] File does not exist: D:/Program Files/Apache/htdocs/favicon.ico

After I googling, there is no good solution on this.  Anything relevant for the root cause?
And meanwhile, I am using: Windows XP with SP3 and Apache 2.2.1

Solution finally identified as follows:

- Downgrade the PHP version to 5.2.X and then it works perfectly.

- PHP Version 5.3.x seems not compatible with Amfphp 1.9.
