I think because by default they have things run in embedded mode. > etc it requires a stop and start (they advise against restart). I certainly would be cautious about using 'restart' a lot as some versions of Python leak memory when interpreter being destroyed. Normally this wouldn't be an issue for command line Python, but in mod_wsgi where new interpreter instance is then created within the same running process, this means that that memory leak occurs in Apache parent process and thus would be inherited from Apache child processes. Thus, use 'restart' or 'graceful' a lot and your Apache processes will grow in size. I have started looking at this memory leak, but because it is in Python itself, not sure how much I can do about it with the way that mod_wsgi is currently implemented. Details can be found at: http://code.google.com/p/modwsgi/issues/detail?id=99 Also, a 'graceful' restart is also a problem at the moment, although effect of the problem is limited. For this, when you do a 'graceful' restart at any point, it would seem that orderly shutdown of Apache daemon mode processes isn't occurring. The process still get killed off, but any Python callbacks registered with atexit module aren't being called.
