You would probably be best to use a hash where the key is the broker you find and the values is the data. Here is an example: 

#!/usr/bin/perl -w

use strict;
my (%brokers, $broker);

# get file contents into an array for convenience
open (CONFIG, "ubroker.properties") || die "Can't Open ubroker file: $
+!";

while (<CONFIG>) {
    next if /^#/;
    chomp;
    $broker = $_ if /^\[.*\]$/;  # found a broker
    $broker = '' if /^\s*$/;     # found a blank line
    # add line to current $broker if there is one
    $brokers{$broker} .= "$_\n" if $broker;
}

close CONFIG;

# keys %brokers returns an array of brokers to iterate over
for (keys %brokers) {
    print "\nBroker: $_\n"; # this is the broker name
    print $brokers{$_};     # this is the data (includes name)
}

If you want to do it with a while(<CONFIG>) you either need to do it in one loop (as you will reach the end of the file after the first loop) or use seek CONFIG, 0, 0; to go back to the begining of the file before you do a second while loop through it.

In this example we use a hash to store both the brokers array (as the keys) and the data associated with each broker (as the values) which means that there is a logical link between the data. If you just wanted arrays then: 

@brokers = keys %brokers;
@data    = values %brokers;
