problem with informix

Hi, I'm struggling with a problem for quite some time. I have a webserver with apache-1.3.22, php 4.0.6 (patched for some security issues), informix ESQL 9.30 and a databaseserver with Informix IDS 7.31. This construction works very fine. As soon as i go to newer versions --> last try : httpd-2.0.43, php-4.2.3, with the same informix configuration the problem appears. Everything went well for about a week --> so it lloks ok, but ... On the databaseserver shared memory gets taken by the php-actions on the webserver and at a certain moment this memory is all used and the server (database) crashes. Is there somebody who has experienced a similar problem or is there somebody who can give some hints in the direction to look for ???
