Mod_perl problem as follows, check out my Mason autohandler, synopsis, at end:

<%shared>
  ## Verfiy we have a cookie with a _session_id
  my $c = Apache2::Cookie->fetch($r);
  if ( exists $c->{'WBT_Session'} ) {
    $c= ($c->{'WBT_Session'}->value)[0];
  } else {
    $m->clear_buffer;
    $m->subexec('/index.html', error => 201 );
    $m->abort;
  }
  ## Verify we have session that matches cookies ID
  my %APACHE_SESSION;
  eval {
    tie %APACHE_SESSION, 'Apache::Session::Postgres', $c, {
      Handle      =>  $dbh,
      Commit      =>  1,
  };};
  if ( $@ ) {
    if ( $@ ) {
      ## No tuple with matching ID (form cookie), bogus data.
      $m->clear_buffer;
      $dbh->rollback;
      $m->subexec('/index.html', error => 301 );
      $m->abort;
  } }
  ## Verify that the sessioned user still has an entry in the users ta
+ble
  ## Save user information into $U by ref
  my $U = $dbh->selectrow_hashref(
    qq{ SELECT * FROM "users" WHERE pkid = ? }, {}, $APACHE_SESSION{'p
+kid'}
  );
  if ( defined $U ) {
    ##@@## HERE IS PROBLEM
    ##@@## WORKS FINE IF I DON'T SEND S ( %APACHE_SESSION REF )
    ##@@## STALLS IF I SEND S!
    $m->call_next( S => \%APACHE_SESSION, U => $U);
  } else {
    $m->clear_buffer;
    $m->subexec('/index.html', error => 101 );
    $m->abort;
  }
</%shared>

<%cleanup>
  $dbh->commit();
  untie %APACHE_SESSION;
</%cleanup>

What happens is this:

1. autohandler, finds a WBT_Session cookie or errors
2. cookie session value refrences _a_session value in session table
3. it reads users id from session table.
4. refrences that userid with user data from user tbl.
5. calls the next mason component in the stack with a refrence to Apache::Session::Postgres object, and a refrence to the user data from user table.

The problem is in the sesion object, at first I figured this would be one thread/fork per process, so refrences would be valid, and but aparently they aren't. If I comment out the the sending of the sesion refnrece everything works fine and dandy, however If i uncomment out session refrence apache just hangs indefinitly.

www.wbt-modules.com, for example of hang up.

anyone have any ideas on how to fix this problem, or even what it is

update

This prolbem is so damn weird, everything works fine if I change this:

if ( defined $U )
  {
    $m->call_next( S => \%APACHE_SESSION, U => $U);
  }

if ( defined $U )
  {
    my %APACHE_SESSION = %APACHE_SESSION;
    $m->call_next( S => \%APACHE_SESSION, U => $U);
  }
