Yeah, if background thread running in C extension module a lot, can cause problems like that. For another take on ensuring a background thread shutdown, see: http://code.google.com/p/modwsgi/wiki/ReloadingSourceCode#Monitoring_For_Code_Changes In that code, rather than use sleep(), waits on Queue with timeout and the atexit registered handler puts something on queue to make thread exit. > Is it intentional that printing in atexit.registered functions does not end up > in error logs like other prints (at least during imports) ? Ensure you are checking both main Apache server log and virtual host error log. Depending on whether you are using embedded mode or daemon mode and in the latter whether WSGIDaemonProcess inside of VirtualHost dictates where it goes.
