Iplanet and persistent postgresql connection

Hi. I've been testing iPlanet Netscape Server. I noticed, that the postgresql connections don't get closed after the script ends. I've tried to close them manually with pg_close but it also doesn't seem to work :-(. I worked out that with Apache I can set MaxRequestsPerChild to 1 and it kills all redundant postgresql processes. But how can I prevent my site from bailing out on iPlanet? (I have to use iPlanet for that project, 'cos my client wants me to do so) Przem
