Hi All,

please help me out with this problem.

While running my mail_out_original.ksh in CRT window, it disconnects from the server saying not connected

Here is my code : (please see the attachment)
____________________________________________________________

#!/bin/ksh

## Load .profile to make sure crontab run jobs are loading all env variables
. $HOME/.profile

## Change into the directory
cd /u/gcsm_admin/mail_out

## Create the touch file
touchfile="/u/gcsm_admin/mail_out/running"

## If there is no other mail_out running the remove the touchfile
NOTRUN=$(ps -ef | grep "mail_out.ksh" | wc -l)
if [ $NOTRUN -le 2 ]
then
rm $touchfile 2>/dev/null
fi

## Exit routine
fnExit()
{
if [ -r $touchfile ]
then
rm $touchfile 2>/dev/null
fi
exit -1
}

## Set a trap to remove the touch file
trap fnExit ERR

## If we are already running then exit
if [ -r $touchfile ]
then
exit
fi

## Create a touch file
touch $touchfile

## Extra process to restart if something hangs
(
PARENT=$$
sleep 600
RUNNING=$(ps -ef | egrep "$PARENT.*mail_out" | wc -l)
if [ $RUNNING -gt 1 ]
then

echo "The pop email processor has been restarted.

Please verify this process actually worked by checking if email from case updates are being sent.

Thanks,

Support" | mailx -s 'MAIL OUT PROGRAM DOWN!' nagarajec@gmail.com
rm $touchfile
/usr/local/bin/killpg $$
exit -1
fi
)&
WAITPROC=$!

cnt=0

while [ $cnt -lt 1 ]
do

## Increment our counter
cnt=$(expr $cnt + 1)

## Run the program
/u/gcsm_admin/mail_out/mail_out.pl
sleep 1
done

## Get rid of the touch file
rm $touchfile

## Kill the monitor process and exit
trap "" ERR
/usr/proc/bin/ptree $WAITPROC | awk '{ print "kill -9 " $1 " 2> /dev/null "}' | ksh
exit 0

your help will be appreciated ...

I suspect that one of your kills is killing the login shell as well as the intended program.

This section of script may be the problem

rm $touchfile
/usr/local/bin/killpg $$
exit -1

I depends what "killpg" actually does. It is not a standard unix command.


Or possibly this area of script which ruthlessly kills parents and children of $WAITPROC.
/usr/proc/bin/ptree $WAITPROC | awk '{ print "kill -9 " $1 " 2> /dev/null "}' | ksh
BTW. Use "kill -9" at your peril. It is a last resort and not a way to end things tidily.
