This script doesn't up the load average, but the process kill with:
kernel: [2094147.207333] test_ping.sh[31552]: segfault at 7fffcc7f3f88 ip 48f62a sp 7fffcc7f3f70 error 6 in bash[400000+ba000]
It's possible the loop generate the error??
I continue investigating.........
I tried to change the loop (change the While for the command for) for(( ; ; ))do with the same result
ontinue investigating.........
