i'd try counting the number of processes first before i'd check for which process-configuration pair needs to be restarted ... here's my version of events ... put in cron to run every minute or hack what you need off it and put in your script in perpetual loop ...
Code:
#! /bin/ksh
numproc=7
a="sam.cfg h20war.cfg cypher.cfg ryan.cfg cell.cfg alls.cfg p31.cfg"
if [ `ps -ef | grep -wc "cod_lnxded"` -lt "$numproc" ]
then
    ps -ef | awk '/cod_lnxded/ && !/awk/' > /tmp/$$
    if [ -s /tmp/$$ ]
    then
        for cfg in $a
        do
            grep $cfg /tmp/$$ > /dev/null
            if [ $? -ne 0 ]
            then
                  /path/cod_lnxded +exec $cfg &
            fi
        done
    else
        for cfg in $a
        do
            /path/cod_lnxded +exec $cfg &
        done
    fi
    rm /tmp/$$ 2> /dev/null
fi

exit 0

mz.cfg(1)						      General Commands Manual							 mz.cfg(1)

NAME

       mz - a fast versatile packet generator

SYNOPSIS

       /etc/mausezahn/mz.cfg

DESCRIPTION

       Mausezahn  is  a free fast traffic generator written in C which allows you to send nearly every possible and impossible packet. Mausezahn's
       MOPS subsystem (Mausezahn's Own Packet System) supports an interactive mode with a Cisco-style command line interface (CLI).  In  order	to
       activate this interactive mode, execute Mausezahn using the -x argument, optionally followed by an arbitrary TCP port number, such as

       # mz -x 99

       in which case you can connect to Mausezahn via

       $ telnet 127.0.0.1 99

       If  no port number is specified, Mausezahn uses the default port number 25542 (which is the date of towel day followed by the answer to the
       universe and everything; however, you don't need to understand this in order to continue).

       Login credentials as well as other MOPS-related parameters can  be  specified  in  the  Mausezahn  configuration  file  mz.cfg  located	in
       etc/mausezahn. Currently, user-specific configuration files are not supported.

       If no configuration file is present Mausezahn assumes the following default login credentials:

	      username: mz
	      password: mz
	      enable password: mops

       Currently only login credentials can be configured within the configuration file. Here is an example content of /etc/mausezahn/mz.cfg:

	      user = herbert
	      password = moTTe
	      enable = T0p5ecreT

       Additional configuration options will be officially supported with the next releases.
