Session object crash apache
---------------------------

                 Key: MODPYTHON-188
                 URL: http://issues.apache.org/jira/browse/MODPYTHON-188
             Project: mod_python
          Issue Type: Bug
          Components: session
    Affects Versions: 3.1.4
         Environment: Gentoo 2006.1 with Apache 2.0.58
Apache details:
# emerge -vp apache
[ebuild   R   ] net-www/apache-2.0.58-r2  USE="apache2 ssl threads -debug -doc -ldap -mpm-itk -mpm-leader -mpm-peruser -mpm-prefork -mpm-threadpool -mpm-worker -no-suexec -static-modules" 0 kB

            Reporter: uka mata
            Priority: Trivial


Starting two times Session crash apache, example:

#!/usr/bin/python
# -*- coding: iso-8859-1 -*-

import sys
from mod_python import apache, util, Session

def index(req):
        req.content_type = "text/plain; charset=iso-8859-1"
        req.send_http_header()
        req.write("Hello world!\n")
        sess1=Session.Session(req)
        sess2=Session.Session(req)
        return "Bye bye!"


When I have reloaded this page several times, apache has stopped to send pages, and I cannot stop it using the init scripts and therefore I need to use "kill -9"

The log said:

Sometimes I have received this page:
Hello world!
