500 error when posting, no message in error logs

Thu Feb 13 19:23:00 UTC 2014

Hi All,

I'm running nginx 1.4.1 on OpenBSD 5.4 stable along with php and php-fpm
version 5.3.27 and mysql 5.1.70 on two systems.  I'm trying to install
piwigo-2.6.1 and running into an issue on of of the systems as indicated by
the subject. 

When I access the site initially it takes me to the setup screen as expected
on both systems.  I enter in the data required and click on "start
installation".  On one system it installs perfectly in less than a second,
in the second system it returns a page that simply says "server error" if i
click on more info it says:

"The website encountered an error while retrieving
http://piwigo.domain.com/install.php?language=en_US. It may be down for
maintenance or configured incorrectly.

Reload this webpage.
Press the reload button to resubmit the data needed to load the page.

Error code: 500"

In the access log I see this:

10.0.0.10 - - [13/Feb/2014:12:50:46 -0500] "POST /install.php?language=en_US
HTTP/1.1" 500 5 "http://piwigo.domain.com/install.php?language=en_US"
"Mozilla/5.0 (X11; OpenBSD amd64) AppleWebKit/537.36 (KHTML, like Gecko)
Chrome/28.0.1500.45 Safari/537.36" "-"

No other information, nothing in the error_log.

I have run diff's on the entire /etc/nginx directory and the only thing that
is different between the two systems is the server name in the
sites-available/<servername.com> files.

I also diffed the php-fpm.conf files and they are identical, php.ini are
identical as well.

I would have consulted the piwigo group, but since it's running perfectly
on, actually 2 other systems with the same OS/software/config combinations,
it seems like there must be something i'm missing on the nginx/php side.

I'm banging my head here, any help would be appreciated.

I have included my configuration files below.

TIA,

Aaron
