Thanks for the quick response PrakashK, but I forgot to mention that I had tried your second option. The results of that made me even more confused as to what was going on. If I call the script from the command line, it will work fine. But it gives me the "overflow" problems if I call it from a file like this: 
#!/usr/bin/perl

my $TIMER = 10;
$TEST = 1;
while ($TEST == 1) {
    do "mrtgnav.pl";
    sleep $TIMER;
    $TEST = 1;
}

Note the $TEST variable. When I run what you see above, it has the problem. But the program works when I try and fool it like this: 
#!/usr/bin/perl

my $TIMER = 10;
$TEST = 1;
while ($TEST == 1) {
    do "mrtgnav.pl";
    sleep $TIMER;
    $TEST = 0;
}

Help. My head is starting to hurt...
