Hi
I used an script to ping all ip addresses in my ocal ip subnet.
I was very slow. In order to make this faster i put ping process in
baground. After 15 second system is dumpimg.
Here is the script
#################################################################
#!/bin/sh -x
class_c=0
class_b=0
subnet=172.16
count=2
while [ ${class_b} != 255 ]
do
class_c=0
while [ ${class_c} != 255 ]
do
ping -c ${count} ${subnet}.${class_b}.${class_c} &
class_c=$((${class_c}+1))
echo ${class_b}.${class_c}
done
class_b=$((${class_b}+1))
done

I tried the same the same on linux and it does not trap the system.
Please advice any ideas how to solve this.
