HELP !!! Too many Connections to Informix Server !!!

Hi people, we are using IIF 2000 (IDS 9.20.UC1-1 with WebDataBlade 4.00UC1) on a Linux server (RedHat 6.1, glibc2.1, kernel 2.2.12-20smp on an Intel Pentium III biprocessor, 512MB ram) with Apache 1.3.12 installed in DSO mode. We have been developing a web application using webdriver (like a dynamic library and as an apache module) and we are going to "release it" on our website. We have encountered a very strange thing. We have noticed we always have a huge number of TCP connections to the Informix Database server. And we have reasons to think they are more than they should be, because the application is still in a test phase and only 1 (yes one) operator is actually working on it (and, unfortunately, not very hard). That's our situation: about 150 TCP connections still active with more or less 50 'oninit' processes. And that's the instant situation (with no real working connection active to Informix): 9 'oninit' processes and 40 TCP connections from different ports. That sucks ... My question is this: is this a typical situation? Should I worry about this or not? If yes (or even if no), are there any configuration options or parameters I can set in order to resolve it? Indeed I find my system is becoming quite slow ... Well, thanks a lot and Ciao -Gabriele
