      Description

      Starting two times Session crash apache, example:

      #!/usr/bin/python

      1. 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:
      [Tue Sep 05 11:42:45 2006] [warn] child process 27269 still did not exit, sending a SIGTERM
      [Tue Sep 05 11:42:47 2006] [warn] child process 27269 still did not exit, sending a SIGTERM

      [Tue Sep 05 11:42:51 2006] [error] child process 27269 still did not exit, sending a SIGKILL

      Sometimes I have received this page:
      Hello world!
