Hi,
You can run the script below as an hourly cron. Works for me.
#!/bin/sh
# clean-up Asterisk zombies
# file clean_up.sh
# $Id: clean_up all dead parent processes
# use as cron task */30 * * * * root /usr/local/sbin/clean_up.sh
#########
##LOG=/var/log/asterisk/agi-cleanup.log
date=`date +%d-%m-%Y_%Hh%Mm`
t1=`cat /proc/stat | grep btime | awk '{print $2}'`
t3=`date +%s`
echo "$date - Asterisk Zombies Clean up started....." #### >> $LOG
echo ""
for parent in `ps -ef | grep safe_asterisk | awk '$3 == '1'{print $2}'`
do
for ppid in `ps -ef | awk '$3 == '${parent}' { print $2 }'`
do
for i in `ps -ef | awk '$3 == '${ppid}' { print $2 }'`
do
t2=`cat /proc/$i/stat| awk '{print $22}'`
b=$(($t3-$t1));
c=$(($t2/100));
d=$((($b-$c)/60));
if [ $d -gt 30 ] ; then
kill -9 $i
echo "Zombie found - killing $i" ### >> $LOG
fi
done
done
done
exit

Asterisk creates threads, not processes.
Trace back from the PPID of the zombies to see who created them
