Is this your entire script or just a snippet? If this is all, this is not 
an AGI.

An AGI is an executable that follows the AGI protocol. At a minimum, this 
means:

1) Read the AGI variables from STDIN.

2) Write an AGI request to STDOUT.

3) Read the AGI response from STDIN.

4) Repeat steps 2 & 3 as needed.

Asterisk creates the process executing your AGI and sends a bunch of cruft 
to it via the process's STDIN. If you don't read this, even if you don't 
need to use the variables, your AGI will not execute correctly and 
reliably.

If you do not read the response after every request, your AGI will not 
execute correctly and reliably.

Most people use an established AGI library since nobody understands the 
implications of the protocol correctly the first time.

Can you enable AGI debugging on the Asterisk console and see if that 
yields any clues?

(Actual 'cut-n-paste' is better than 'retyping' console output.)

I think if you take another look, this is a warning, not an error. No big 
deal, it means just what it says, just ignore it.
