If your script prematurely exits, then how will the clean up part run?
You should look at the trap event and create a trap event for exit.
Then if the script errors out, the trap event gets called and can run.

It can be as simple as this. You will need to check the syntax and make
sure that it works under a variety of circumstances.

Code:
#!/bin/ksh 

run_exit_function () {
if [ "$(grep -c 'Application  Failed' /home/sanity_logs_$DATE)" -eq 0 ]  ; then 
 
  echo "False Alarm  "| mailx -s "False alarm" abc@gmail.com 
  rm -f /home/sanity_logs_$DATE 
else 
  { echo 7; while [1]; do echo c;done;} | start_up
  echo " Failure resolved 
         Below are the processes running 
         $(sanity) " | mailx -s " Failure resolved " abc@gmail.com 
fi
}
 
trap 'run_exit_function' exit

DATE=`date +%Y%m%d` 
 
sanity > /home/sanity_logs_$DATE

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
       directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script,  service  passes  COMMAND and OPTIONS it to the init script unmodified.  All scripts should support at least the start and
       stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the  start
       command.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
