No you cannot change the network keep alive timeout, or not readily and it isn’t something you should ever do. It is quite possibly nothing to do with that anyway.
As to WSGIApplicationGroup then it may help as I already outlined. Any reason you haven’t tried it as it is recommended practice to use it? What exactly are you using simpy for anyway. Looking at the documentation for it it does various stuff with sub processes. Heavy or complicated use of sub processes from inside of the context of a web application, especially under Apache/mod_wsgi, is generally a bad idea. This is because it may not play well with Apache’s process model and so something like simpy may not work properly or could even interfere with the process management of Apache or mod_wsgi.
