in reply to Kill and free the memory Never ending threads from main

But when I am exiting the threads are still running I want to free all the space occupied by this threads and then exit from the script

When your main thread exits; any other threads will be killed and cleaned up automatically.

If you wish to suppress this oh so useful informational message:

C:\Downloaded\testp>perl -Mthreads -E"async{ sleep; }; say 'hi & bye';
hi & bye
Perl exited with active threads:
        1 running and unjoined
        0 finished and unjoined
        0 running and detached

Just detach the threads:

C:\Downloaded\testp>perl -Mthreads -E"async{ sleep; }->detach; say 'hi
+ & bye';"
hi & bye
