Adobe AIR Corrupting JSON data?

I am experiencing a very strange issues with Adobe AIR truncating JSON responses randomly.

I have an AIR application which communicates with a server process via JSON. The issue I am experiencing is that the server is sending a valid JSON response but AIR seems to be randomly truncating some responses prematurely.

I installed charles web proxy to look at the HTTP request and verify that the JSON that is being returned is valid.

The JSON that the server returns and which the web proxy sees arriving is is :

{

    "responseType":"closewindow",

    "text":"SYSTEM IS BUSY DOING SYSTEM ADMINISTRATION WORK!",

    "delay":50000,

    "logout":false

}

But when I look at the JSON in Introspector all it sees is :

{

    "responseType":"closewindow",

    "text":"SYSTEM IS BUSY DOING SYSTEM

Does anyone have any ideas or similar experiences with AIR getting truncated http responses in introspector?

Any help would be greatly appreciated!
