Dear monks , can you throw some light on below issue as i am unable to figure out why my hash structure is messing up while referencing array as the key value. I had done the same is past for another script and conceptually it works but somehow in this case not sure whats wrong. My code is below. I have added all but just the main logic where hash is generated

 
my %parCode = (
                0 => "partition-1",
                1 => "partition-2",
                2 => "partition-3",
                3 => "partition-4"
            );

        while (my $in_line = <INFILE>) {
        @time_arr = ();
        chomp($in_line);
        if ($in_line =~ /Registered listener on template/){
           #print "$in_line\n";
           @row = split('\s',$in_line);
           ($r{time},$r{partition}) = ($row[0],$row[-1]);
           $r{partitionName} = $parCode{$r{partition}};
           #print Dumper(\@row);
           #print Dumper(\%r);
          if (exists $parMap_ha{$r{partitionName}}){
            #print " >> ### Time event detected -  $r{partition} - $pa
+rCode{$r{partition}}\n";
            #print Dumper(\%parMap_ha);
                              push(@time_arr,@{$parMap_ha{$r{partition
+Name}}},$r{time});
             #print Dumper(\@time_arr);
                                $parMap_ha{$r{partitionName}} =\@time_
+arr;
             #print " << ### post modification \n";
             #print Dumper(\%parMap_ha);
                        }
                        else{
                                $parMap_ha{$r{partitionName}} =[$r{tim
+e}];
              #print " >> *** 1st event detected - $r{partition} - $r{
+partitionName}\n";
              #print Dumper(\%parMap_ha);
                        }
                }
        }

Below is the hash dump with infile data where you can see that this works for the 1st few iterations and later the hash messes up
