PHP mem leaks

After being told off on the dev list I have posted this on this list (I thought it was techie enough to go on that list but I was wrong....) I am running a large PHP/MySQL/Apache driven website and I am finding that the apache Processes get larger and larger as the days go on. When I stop/start apache the processes are around 16-17 meg each and after a week they are about 40meg each and if we then get a large in flux of traffic say a Monday lunch time the server just pages out and dies... I have been on the apache list given them all my modules that I have running and they pointed the finger at PHP, I was told to change maxrequestsperchild to 100 but this made no difference. Is there a fix for this? or a planned fix for this? Oh and here are the modules I am using: We are running Apache/1.3.26, PHP/4.2.2 mod_ssl/2.8.9 under FreeBSD 4.6. Apache modules: mod_php4, mod_ssl, mod_setenvif, mod_so, mod_auth, mod_access, mod_alias, mod_userdir, mod_actions, mod_imap, mod_asis, mod_cgi, mod_dir, mod_autoindex, mod_include, mod_status, mod_negotiation, mod_mime, mod_log_config, mod_env, http_core all compiled in except for mod_php4 and mod_ssl which are loaded using LoadModule.
