When you say under Apache, do you mean with mod_perl?

If so then it is quite possible that the script you are running never actually loses the object (eg it is in a global variable), it survives because it is in a persistent processs, and DESTROY is never going to be called.

Try using Apache's register_cleanup function to register a function that does your cleanup. To do that you will need to keep track of the created objects, and then do the save in your cleanup function. I haven't done that myself, but recent versions of CGI.pm first check whether $ENV{GATEWAY_INTERFACE} exists, and if it does then does it match /^CGI-Perl\//. If it does then mod_perl is on, they require Apache, then later on: 

    if ($MOD_PERL && defined Apache->request) {
      Apache->request->register_cleanup(\&CGI::_reset_globals);
      undef $NPH;
    }

The $NPH doesn't concern you. The Apache->request bit does. You might do that by having in your constructor something like this: 
    if ($MOD_PERL && defined Apache::Request) {
      Apache->request->register_cleanup(\&saveall);
      push @OBJ_STORE, $self;
    }

and then in saveall save each method in @OBJ_STORE then discard them all. (Check in your DESTROY whether things have been saved.)

This is untested, but give it a shot and see if it doesn't work.
