problem with the my wrapper script

Hi friends,
i am working in ksh88. i am running the follwing wapper script in background to run two jobs parallely((eg nohup wrapper.ksh &)::

wrapper.ksh
########################
Code:
#!/bin/ksh 
nohup ./pii_insert.ksh  /nsing83/p2/test  & 
nohup  ./pii_update.ksh nsing83/p2/test & 
 wait 
echo "the wrapper script is done"


######################

->the wrapper scripts is running fine if it is running for few hours. but when it is required to run for the more than 10 hours , then it is not waiting for the two sub process to complete and it is getting killed before that.(i.e it is not printing the last echo line)

please help.SmilieSmilie

try it this way.
capture the process id of sub process and keep checking for completion in a loop after some interval.
Code:
wrapper.ksh
########################
#!/bin/ksh

nohup ./pii_insert.ksh /nsing83/p2/test 2>&1 &
# Capture pid of process and write into file
echo $! > subprcs_pid

nohup ./pii_update.ksh nsing83/p2/test 2>&1 &
# Capture pid of process and write into file
echo $! >> subprcs_pid

# Wait in a loop (5 minutes sleeps) while the pids are still active.
if [[ `cat subprcs_pid |wc -l` -gt 0 ]]; then
        PIDS_ACTIVE=1
        while [ $PIDS_ACTIVE  -ne 0 ]
        do
                sleep 300 
                for PID in `cat subprcs_pid`
                do
                        # ps -p returns 2 rows if the pids are active else one row
                        ACT_PID=`ps -p $PID|wc -l|tr -s " "`
                       if [ $ACT_PID -eq 2 ]; then
                                PIDS_ACTIVE=1
                                break
                        else
                                PIDS_ACTIVE=0
                        fi
                done
        done
fi

echo "the wrapper script is done"
