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!
