First let me describe the architechiture. We are running Apache 1.3.27 with PHP 4.3.1 that connects to a SQL Server Database on WinNT Server 4.0.

Here's the problem: when a web request is sent to Apache....just a single request, the memory usage on the Apache.exe process jumps to like 500MB instantly...the CPU usage however remains low like after the request the CPU is not being used anymore.....the link works when click but if you click it again the server will crash due to too much mem usage. The PHP script accesses a custom extension DLL and the extension dll accesses a custom system DLL. But the thing is, this works in many other setups....the only thing different about this setup from the rest is the system runs WINNT instead of 2000. Has anyone seen this? I really doubt it is my code causing the problem since it works many other places (not saying i'm perfect just saying it really doesn't act like its the code i wrote).

Thanks in advance!
