Hello Monks.
I wrote a little script, for sorting out some traffic statistics. It parse log file putting all into big hash(I guess its gettin really big) and then print formatted output. The problem is when size of log files exceed about 200mb, it eats all the memory(512mb) and I got error: "Out of memory during request for 1012 bytes, total sbrk() is 536797184 bytes!"
What should I do with that?
Here is my code: 
while (<LOG>){
        my ($source, $sport, $to, $dport, $proto, $packs, $bytes) = sp
+lit;
        if ( $total{"$source$dport"}{'from'} ) { # if source exist
                $connects{"$source$dport"}++; 
                if ($total{"$source$dport"}{'to'}) { # and destination
+ exist - summarizing
                        $total{"$source$dport"}{'bytes'}+=$bytes; }
                else { print "oops"; } # this seem we can't get here, 
+but I don't get why...
        }
        else { $total{"$source$dport"} = { "from" => $source, "to" => 
+"$to:$dport", "bytes" => $bytes } }
        $total+=$bytes;
}
