right. locking doesn't help in this case. ;-)

however - isn't there a possibility to
a) generate something like "a socket for each local connection attempt" (ResourcePool::Factory ??) within the deamon.pl, which collects the different application.pl's data and
b) pump the data from the different socket connections to a "general/shared queue" in deamon.pl

like this pseudo-code deamon.pl:
$queue = generate_global_ressource();
create_socket_pool(max_sockets = 200);
while(1=1){
    if($input=connection_attempt) {
        if($input ne 'finish') {
            push($fetched_data_from_socket, queue);
        } else {
            close_socket();
            create_new_socket_in_socket_pool();
        }
    }

(where generate_global_ressource() is something like ResourcePool::Command::DBI::Execute)

because all i need that deamon for are INSERT statements, the applications don't need to wait for return values. they should only "dump" the sql statements to a socket without caring what happens. (also there is a quite generous error-tolerance here: i don't care for lost data, as long as it doesn't exceed 5-10%...)

i still don't get:
a) how to keep a number of opened sockets in stock for the different application.pl which all use THE SAME port; and
b) how to use deamon.pl's general $queue AS a general queue for the several connection instances...
