Apache crashes on segmentation fault using mod_wsgi large xml files

I'm getting a segmentation fault in apache, causing it to restart automatically. The setup is as follows:

  • server is a wsgi application generated using python spyne (currently running on localhost)
  • soap call is done from a WPF application (.NET)

  • using apache 2.4 on windows, with configuration for mod_wsgi as follows:

    LoadModule wsgi_module modules/mod_wsgi.so

    WSGIScriptAlias /WSGI "C:/...etc...pythonservice.py"

    WSGIPythonPath "C:/...etc..."

    WSGIApplicationGroup %{GLOBAL}

    Directory "C:/...etc..."

    Order deny,allow

Allow from all

    /Directory

I think the problem might be a default 10MB size limit on XML nodes (libxml2), but I can't find any solution to this problem for my particular set-up.

After a switch to Visual Studio 2013, I got a different error message, namely ContextSwitchDeadlock. This answer solved my problem:

During loading of the large dataset, after every 1000th item I called System.Threading.Thread.CurrentThread.Join(10) to make sure the application keeps pumping messages.
