[asterisk-users] Asterisk 1.4.30 is slow sending STDIN to AGI script

[Danny Nicholas]

FWIW, I would take your STDERR references and give them another handle,
since you're not really trying to produce a CLI/Console output.

The symptoms you have described in this thread are 100% compliant with "AGI
protocol violation (their term not mine)" - the last suggest I would give
you is to do an implicit AGI usage like this:
my $agi;
my %input;
$agi = new Asterisk::AGI;
%input = $agi->ReadParse();

I dont think that routine is the issue. Its only called when setting the 
  variables and that is only done before the call is dialed and in that 
case the script generates no errors :-

The problem is with where the mode is answered or completed when I get 
errors like this :-
