Blank/Empty RRD Graphs Page (PHP Crashing)…

[ksoviero]

When attempting to visit the Status > RRD Graphs page, I am greeted with a blank page…  Most likely due to PHP being unable to complete the request...

I am unsure how to repair this.  On Linux I would usually run something akin to the following to discover the problem, but I can't do this on pfSense (AFAIK):

su -l apache -c 'strace php /usr/local/www/status_rrd_graph.php'

Any theories?

Just to demonstrate how little is returned by PHP:

$ wget https://XXX.XXX.XXX.XXX/status_rrd_graph.php --no-check-certificate -O -
