Managers, Thanks to all who replied, espically to Dr. Thomas P. Blinn and Dr
Tim Cutts
The while loop several people suggested were owned by 1 when killing the
shell.
The one i popped for was a perl script:
Try the following perl script. This is a *really* nasty fork bomb, so
don't run it on a production system. Some systems behave very badly if
you do this to them :-)
#!/usr/bin/perl
my @pids = ();
my $pidcount = 0;
my ($pid);
while (defined($pid = fork)) {
if ($pid) {
push (@pids, $pid);
$pidcount++;
} else {
@pids = ();
sleep 3600;
exit 0;
}
}
if (@pids) {
kill 9, @pids;
print $pidcount, "\n";
}
