I posted an inquiry a couple of days ago regarding the behavior of Store_fd. I found out that this wasn't the problem. The thing is that I'm trying to serialize an object and I'm trying to do it with "Storable". I open up a file and when I write into it with store_fd it doesn't do it. I just found out that somehow a function that I am using is closing the file or redirecting the file descriptor in some manor. The following is an extract from my code to see if anybody can help me: 
    local *F;
    open (F, ">$file") || die "Error opening $file: $!\n";
    my ($id, $obj);

    while (($id, $obj) = each %$all_instances) {    
        my $class = ref($obj);

    my @attrs =
        $obj->get_attributes(@{$this->
                            get_attrs_for_class($class)});

        ### I discovered that after this line of code,
        ### it either closes the file or redirects the 
        ### file descriptor.

    my @array = ($class, $id, @attrs);
    
        Storable::store_fd (\@array, \*F);

    }
    close(F);
