When pipe-spawning children, I usually follow this pattern to clean up stray detached child processes:

my $CHILD = open2(\*READ, \*WRITE, "$TSHARK $TSHARKOPTS") ||
        die "Can't open2 child process: $!";
push @children, $CHILD;
END { kill 9 => @children; };

Of course, this simple approach is no good if you have a machine where PIDs get recycled very fast, or if you have a long running process with many children that have finished. Then a cleanup of @children if a child finishes is in order.
