Folks,

I switched off selinux in an attempt to fix this, but it turned out the
issue was root only rwx permissions on /var/logs/httpd.  For some reason
the default pipe creation location is under this.

I have taken the liberty of making this log directory world readable and
traversable and now fastcgi access is working.

eg.

http://localhost/cgi-bin/mapserv.fcgi?map=/opt/msmaps/raster.map&SERVICE=WMS&REQUEST=GetCapabilities

on the server itself.

At this point I believe we are ready to start performance testing the
MapServer raster configuration, though I will at some point want to also
build a development-trunk version of mapserver which includes a few
performance improvements likely to help performance.

Best regards,
