Don't assume the daemon runs in a certain directory. The working
directory of a daemon should generally be '/' unless it is chrooted for
security concerns.

So please provide the full path to the script. Anyway, scripts don't
belong in /etc/asterisk. There is enough junk there already.

So let's start ruling out reasons:

1. use full path

2. System(ls -l /path/to/BuildMsg.sh >/tmp/output)

3. System(strace -o /tmp/trace /path/to/BuildMsg.sh 1-1 msg02 msg99)

Distro? Kernel? Glibc?
