Safe perl threads

I'm trying to run a perl script with threads using the detach methode. The application is supposed to run permanent, 24/7. I'm trying to use the this example.

But when i run this example in a longer time period it turns out that there is a constant increase of memory. How can i avoid this? How can i use the threads->detach method without the increase of memory?

Can you post your code or what you are trying to detach?

you dont need to use pool.pl just to run a detached program.

The simplest you can do is

use threads;
use threads::shared; # if required,


###loop main prog

my $detach_thread = threads->create(

    sub {
         # DO YOUR STUFF here
          return;
        }

);

$detach_thread->detach();

Other alternative to consider is running in background (in unix: yourcommand &).

Another approach may be the use of Parallel::ForkManager module (A simple parallel processing fork manager). I have used it and I get my work done (long running processes without memory leaks).
