You're use of $key in the inner loop is incorrect.

Yours is too... a hash reference cannot be stored (directly) as a hash key, only as value. so that should look like 

my %Data = getQueues();

while (my ($key,$value) = each(%Data)){
    #print "$key = $value \n";
    for(my ($k,$v) = each(%$value)){
        print "$k = $v \n";
    }
}

although that snippet doesn't fit the OP's data structure, either. The following might work: 

while (my ($key,$value) = each(%Data)){
    if (ref $value eq 'ARRAY') {
        for my $hashref (@$value) {
            print "  $_ => $hashref->{$_}\n" for keys %$hashref;
        }
    } else {
    print "$key = $value \n";
}
