I'm suspicious that Odoo which runs behind nginx in a reverse proxy
config could be creating too many connections or something similar and
bogging things down for my main site which runs in apache2 behind
nginx as well. Is there a good way to find out? Stopping the Odoo
daemon certainly kills the problem instantly.
