asterisk users - Sep 2003 - festival problem

I have loaded festival-1.4.3 patched with the 1.4.3.diff file.  Festival source
is in /usr/src/festival dir.  When I try to use it I get this from asterisk:

    -- Executing Answer("SIP/chad-57a4", "") in new stack
    -- Executing Festival("SIP/chad-57a4", ""I am
talking"") in new stack
  == Parsing '/etc/asterisk/festival.conf': Found

  == Spawn extension (local, 521, 2) exited non-zero on 'SIP/chad-57a4'

And this from the festival server:

SIOD ERROR: unbound variable : I


I have done this twice, and came up the same way both times.  I followed
directions from http://www.marko.net/asterisk/archives/0209/0389.html and used
the 1.4.3 instead, everything else is the same.

Any help is apreciated

I have Festival running fine on one Fedora Core 3 machine but I am
having problems getting it to work on another one.
I am using festival-1.4.2-25
I have followed the guide at
http://www.voip-info.org/wiki-Asterisk+Festival+installation and am
using the second festival command patch which is the same one I use on
the working server.

The festival logs show the following on the working machine:-
"Load server start ./festival_server.scm"
 festival port=1314
wrapper Thu Mar 17 14:59:10 GMT 2005 : USING DEFAULT CONFIGURATION
wrapper Thu Mar 17 14:59:10 GMT 2005 : waiting

On the working server asterisk shows :-

On the non working server asterisk shows:-

    -- Executing Festival("SIP/6152-d2ec", "mary had a little

Any idea what is wrong?
What is this 'remote UNIX connection'?

Thanks

I'm attempting to use Festival with Asterisk on an x86_64 system.  This 
IVR application works ok on a P4 system.

I'm using the FC3 x86_64 distro on a single processor Opteron system. 
Festival by itself (using the command line and speakers) seems to work 
ok, and Asterisk without Festival works ok.  When the Asterisk dialplan 
calls Festival, however, Festival reports a disconnect and Asterisk's 
Festival command does not complete. Later, when I shut down the system 
for reboot, I get a kernel panic.

I've tried both the FC4 Festival rpm as well as the source download from 
festvox.org.  I modify the siteinit.scm file as per the wiki page, and I 
use the stock festival.conf file in Asterisk.

Has anyone experienced this behavior, and is there a workaround?

Thanks,
