Is there a reason you are using "tail -f" in your file handle, as opposed to "tail -n 10" or similar. In my system, the script hangs waiting for additional input to the file. Here's an alternative idea for you to consider: 

my @list;
my $file  = q[/path/to/some/file];
my $regex = qr[your pattern]; 
open my $fh, "tail $file |" or die;
while (<$fh>) {
    chomp;
    say "testing: $_";
    push @list, $_ if ( $_ =~ $regex);
    last if (@list >= 2);
}

local $"="\n";
say "found: @list";
