I'm working on a perpetual program. It runs indefinitly, checking on various servers using ping or SNMP queries. It works like I want it to but it has one major problem. It continualy grabs and uses more ram and process time with each iteration, growing until it become a detriment to the system it's running on.

I have a secondary script, an outside file, that I open and eval. Would this be bloating the memory? This file is simply a hash of data that may change while the script is running. I've set the program up, so that the data can be changed while the script is running. 

open(DATA,"data.pl");
   while (<DATA>) {$data .= $_;}
close DATA;

eval $data;

Here's an example of the data it's calling. 
@array = (
        { label => "backup.hostname.com",
        status => "on",
        type => "ping",
        data => "hostname.com",
        user => user@hostname.com,
        error => 'Failed',
        },
);

But i digress, what I'm looking for is some tutorials on memory management. Where can I find this information, and how can I trim a bloated program while it is running. Similar to undef, but will actually free the memory up for the system.
