Hi, 

foreach my $prime_id ( @id_hits ) {
        $line = shift @log until $line =~ /$prime_id/;

you're shifting elements off @log on the first run.
@log gets shortened this way.

Think of the first $prime_id not found in the logfile at all this will result in @log being empty on the second run of the foreach loop. Did you consider this?

I'm not sure about the structure of $prime_id's in relation to the logfile's content but it may result in some unpredictable results.

Hope this helps.
