I'm running a WSGI app under apache/mod_wsgi and I've noticed that
whenever I restart the server after making a code change it takes a very
long time (like a minute) before the script is active again. In other
words, I do an apachectl restart, reload the page in my browser, and one
minute later it finally comes up. During this time CPU usage is
essentially zero. Loading all the code manually into a python
interpreter is virtually instantaneous, and all subsequence interactions
with the app are very fast.
Does anyone have any ideas what might be going on or how to debug this?
strace is nice. It sounds like some blocking network operation. rdns can
often cause things like this. If you're lucky, strace will point right at
the problem.
