[csw-maintainers] fontconfig => rrdtool slowness under Apache

[Daniel Pocock]

There are many discussions around the web about rrdtool running slowly
in various situations

In my case, I found "rrdtool graph" runs slowly (4-5 seconds per graph,
even on a very powerful machine) when generating the graphs for Ganglia
web pages.  This is on a fresh install of the CSW packages of Apache2,
PHP5, rrdtool and fontconfig.

In my case, I found that

chown nobody /var/opt/csw/cache/fontconfig
chown nobody /var/opt/csw/cache/fontconfig/*

immediately resolved the issue.

On the machine in question:

Apache process runs as nobody
nobody has shell /usr/bin/false
nobody's home = /

Can anyone suggest where the blame lies?  Is there any other information
from my environment that may be helpful in fixing this?
