Hi all,
I have config:
Django 0.91, apache 2.0.55, mod_python 2.3.8, Win XP.
When I test my app by page requests from different browsers at the same
time (concurrent access testing), I receive errors like these:
=====================================
-- when 2 clients attempt to get page:
Mod_python error: "PythonHandler django.core.handlers.modpython"

As I guess, by some reason connection or cursor are closed by
other/older request. But may be I'm wrong. Has anybody similiar flaws
and if yes, how you solve them?
Note: I have no problems with 1 user access using this env, also DJ
development server is stable in multiuser access.
Thanks in advance,
Alex
