I am already preloading thanks to your Sydney presentation. When I try to recreate the problem, I am surprised to find that I am having a hard time creating the problem with apache and mod_wsgi, so I am wondering now if the behavior I see only occurs when I run the app with paster instead of apache/mod_msgi?
*Should* this be completely safe? In other words, if an application process is just starting and apache receives an http request, is there a mechanism in place such that it will properly, patiently wait for mod_wsgi to load the app completely before the request is fed to the process? (I can readily demonstrate that this is not the case when paster runs the app.) Thank you for your time, Kent On Sep 16, 5:00 pm, Graham Dumpleton <[email protected]> wrote: > On 16 September 2011 23:44, Kent <[email protected]> wrote: > > > Is there a way to force a delay (arbitrary or determined) so that when > > apache restarts, it waits until the python app has loaded completely > > before allowing requests to be taken by the process? > > > Our application stems from a turbogears project.
