[ Error] Segmentation fault (11), code=1, addr=0x8

------------------------------------
# I have cgi script like:
echo "Content-Type: text/plain"
echo
echo -e "Fetch date: $(date -u +'%F %T %Z')\n===================================\n\n\n"
ssh -o 'ControlMaster=no' -o "StrictHostKeyChecking no" -i /etc/monkey/keys/se-monkey-ssh-key login@host.domain.com "/some/long/processing/command"
------------------------------------

When I open "url" adres pointing to this cgi script in my browser I wait a while - but it works.
But when I open "url" adres pointing to this cgi script in multiple tabs in my browser
monkey crashes with:

    [  Error] Segmentation fault (11), code=1, addr=0x8

Any one had the same issue ?
Do You need more info ?
