[Asterisk-Users] Asterisk and Festival (* dies with no info)

[Chris Albertson]

"strace" might give you some helpfull info.  See man strace.
It will record system calls and signels.

Given what you say I'd run Asterisk in a debugger.  I like
"DDD"  Compile everything with the -g gcc option first
so the debugger can display source code lines.  In DDD when
the program stops the curser will be left on the last line
executed and you can cause it to "run backwards" and see
how you got there. 

Also, are you sure the Asterisk process died and isnot just
hung either in an infinite loop or waiting for something
that will never happen?  What doe "ps" say?
