Hi, I am running mod_python 3.1 under Apache 2.0.50.0 and Windows XP. I am building a database driven web site using Python Server Pages and a MySQL back end (using the ADOdb module). The site is up and working fine. My problem is that when I try and do a primitive load test by reloading the pages very, very quickly, two critical bugs appear. The first problem is that sometimes the req.uri mysteriously changes from "/home.html" to "other.html" Here's the source code in my handler script: ---------------------------------------------- from mod_python import apache, psp, Session, util ##import wingdbstub import sys import os import traceback import time import initModule def handler(req): #Standard out should print to the browser for debugging oldstdout = sys.stdout sys.stdout = req print req.uri # Here req.uri always prints out "/home.html", even when reloading quickly print "1" init = initModule.InitClass() init.req = req print init.req.uri # Here req.uri also prints out "/home.html" until I start reloading too quickly. Then it prints out "/other.html" What's going on here? Are somehow the two requests trying to access the same object? But why does it say "/other.html"? From what I can tell, the word other.html is not used a single time in any of my scripts nor does other.html exist as a file. I've gotten the same problem in both Firefox and IE. I never have any problems running PHP scripts. The second problem is that sometimes the request just hangs, and then Windows gives me a message saying "Apache.exe encountered a critical error and was forced to shut down" I thought that some kind of threading problems might be the issue. I've looked through all my modules though, and from what I can tell not once do I modify module variables (I only read the variables and call functions). Also, for the database connection I am using a pool, whereby new connections are created if existing ones are being used. I do have PHP installed in the same Apache, but it's not being actively used. I also edited the Apache conf file and set MaxRequestPerChild to 1, but that did not solve the problem either. Has anyone else had these problems? Can anyone help me? I'm going to try uploading the site to my Linux Virtual Private Server (I'm only running mod_python on XP so that I can do development on my laptop). Hopefully this problem is just a Windows issue. Otherwise I don't see how I can use mod_python. Help greatly appreciated, Patrick
