My Flask and mod_wsgi app seems to be breaking ports. Every month or so my
page will stop loading and I get a "Google Chrome could not connect to "
message, but moving it to a new port fixes it. I've checked the apache log
and there doesn't seem to be anything wrong there. If I stop apache from
listening to the port and run my dev version of the Flask app on one of the
ports that the live version has previously used I get the same "Google
Chrome could not connect to " message. While apache is listening Netstat
shows that the port is being listened to by apache and lsof -i returns a
bunch of apache processes that are using the port. I'm not sure if any of
that is normal for mod_wsgi. If I remove the port from apache both netstat
and lsof return nothing but the port still doesn't work for mod_wsgi or
flask.
Here is the mod_wsgi part of my apache config file with the ip, domain, and
user/group changed
<VirtualHost 0.0.0.0:8880>ServerName test.example.comDocumentRoot /var/www/html

from dashboard import app as application

this_dir = os.path.dirname(__file__)
log_file = os.path.join(this_dir, 'production.log')
file_handler = logging.FileHandler(log_file)
file_handler.setLevel(logging.WARNING)
application.logger.addHandler(file_handler)
