Return codes can be set by you, or can be returned from the scripting language you work in.

If you were working in Perl, for instance, a return code of 4 means Interrupted System Call.

Check the documentation for your language for a better idea. Also try running your script as the user that Asterisk runs as. Maybe asterisk doesn't have permissions to execute the script. One way to do this is via the "sudo" command, e.g. sudo -u asterisk <path to agi-script>
