program.sh is working for me.
Anything else doesn't, no errors. I have tried this exhaustively. I think I'll just give up cause its driving me nuts.

The actual scripts I wrote are much longer. It didn't work for them, and when I narrowed it down this was the main problem.

Okay, so my fault here I over simplified my example in OP.

This is more of what I'm doing which for the line previous to the send_nsca binary program is not working:

in shell:

Code:
echo "host,log,0,message" | program_below.sh

program:

Code:
while read -r line; do
  STRING=$line
        echo $STRING > /usr/local/nagios/syslog/debug #and I see no output in debug file
        echo $STRING | /usr/local/nagios/libexec/send_nsca -H 192.168.93.55 -d ',' -c /usr/local/nagios/etc/send_nsca.cfg #this works
done

HELP!!! LOL Smilie

These are all working, my bad, but for some reason they didn't before.

Solved the problem.

I am using syslog-ng program() as a destination for a log.

Apparently, the problem has to do with the absolute path in the script. I'm guessing if calling with program() it leaves the directory that script is called from, so the absolute path is necessary. Either way, it works now to:
absolute_path/debug.log

Thanks for the response, hours upon hours again wasted for nothing, I will ALWAYS freaken add an absolute path to every line of every script from now on. Lesson learned.

SERVICE(8)						    BSD System Manager's Manual 						SERVICE(8)

NAME
service -- control (start/stop/etc.) or list system services SYNOPSIS
service -e service -R service [-v] -l | -r service [-v] <rc.d script> start|stop|etc. DESCRIPTION
The service command is an easy interface to the rc.d system. Its primary purpose is to start and stop services provided by the rc.d scripts. When used for this purpose it will set the same restricted environment that is in use at boot time (see below). It can also be used to list the scripts using various criteria. The options are as follows: -e List services that are enabled. The list of scripts to check is compiled using rcorder(8) the same way that it is done in rc(8), then that list of scripts is checked for an "rcvar" assignment. If present the script is checked to see if it is enabled. -R Restart all enabled local services. -l List all files in /etc/rc.d and the local startup directories. As described in rc.conf(5) this is usually /usr/local/etc/rc.d. All files will be listed whether they are an actual rc.d script or not. -r Generate the rcorder(8) as in -e above, but list all of the files, not just what is enabled. -v Be slightly more verbose ENVIRONMENT
When used to run rc.d scripts the service command sets HOME to / and PATH to /sbin:/bin:/usr/sbin:/usr/bin which is how they are set in /etc/rc at boot time. EXIT STATUS
The service utility exits 0 on success, and >0 if an error occurs. EXAMPLES
The following are examples of typical usage of the service command: service named status service -rv The following programmable completion entry can be use in bash(1) for the names of the rc.d scripts: _service () { local cur cur=${COMP_WORDS[COMP_CWORD]} COMPREPLY=( $( compgen -W '$( service -l )' -- $cur ) ) return 0 } complete -F _service service SEE ALSO
bash(1) (ports/shells/bash), rc.conf(5), rc(8), rcorder(8) HISTORY
The service utility first appeared in FreeBSD 7.3. AUTHORS
