asterisk users - May 2007 - Trixbox drops call after running AGI script

Hey, I'm hoping somebody knows the answer to this.

The script works fine on the old Trixbox 1.0 but have recently upgraded 
(just testing in VMWare) to Trixbox 2.2
What happens is Trixbox will drop the call after I call the AGI command 
in my dial plan.

I first of generate a call file to call the user, then connect them to 
an extension in the dial plan

[voice-report]
exten => 1,1,Answer()
exten => 1,2,AGI(call-logger.php|${userid})
exten => 1,3,Playback(custom/welcome)
exten => 1,4,Playback(custom/report06)
exten => 1,5,HangUp()
exten => h,1,DeadAGI(call-cleanup.php|${userid}|"CHANUNAVAIL"})
exten => failed,1,DeadAGI(error-logger.php|${userid})


call-logger.php works perfectly but its just after call-logger that 
Trixbox will just terminate the call.
it still runs the other scrips  (error-logger.php) so its not like the 
service crashes.

I notice after a entire reboot of Trixbox the script runs fine for one 
call then it mucks up again.

All the php files do is log the passed variables into a database so they 
don't interact with
Trixbox in any other way.

Any help on the matter would be greatly appreciated.

Kind regards,
Allan..
