Thanks for everyone's suggestions.

thraxil suggested that misused array's might be my problem. It seemed a good place to start

My goal is to save an array reference which contains, at most, 10 datapoints. Every 60 seconds I get the array reference and add to it (dropping older off first)

In addition to knowing if there is a problem in the code, I would appreciate "coding" suggestions as I am new to Perl.


my @tmp;
my $cur_qty;
if (!defined $Output{"host"})
 { $cur_qty = 0; }
else
 { @tmp = @{$Output{"host"}}; $cur_qty = @tmp; }

if (!$cur_qty)
{            
 # No saved data, just assign it
 $tmp[0] = $data;
}
elsif ($cur_qty >= 10)
{
 # Remove oldest
 shift @tmp;
 # Add newest
 push @tmp, $data;
}
else # Just append it
{
 push @tmp, $data;
}

# Save it
$Output{"host"} = \@tmp;
