Hi
I am experimenting with nginx and php5-fpm to replace an
apache2/libapache2-mod-php configuration. And I am getting something
strange happening.
I have both a simple php web site that just consists of php pages (and
other assets) and static content.
I also have a wordpress configuration.
What I am finding after an idle period (do not actually know how long it
has to be, but I am leaving the web site and coming back after a couple
of hours of doing something else) is that
The static web site works,
the wordpress web site doesn't - because it appears that php5-fpm is
returning a 500
php5-fpm still appears to be running with the right number of processes.
I can get the wordpress site to work if I restart php5-fpm.
The question is why. The main difference that wordpress site has is
that it uses a mysql database. But I have no idea why that might cause
failures after an idle period.
Anyone any other ideas?
