        I didn't see a startup.pl file with IDS.  The previous poster detailed the httpd.conf 
configuration necessary for IDS, although the issue of the startup file and module preloading was not  
addressed.

        512M is not as much memory as it seems with modperl because each httpd child can chew up many  
double-digit megs of memory.  I don't use modperl on servers with less than a gig.  It really depends          
on how much traffic httpd is getting (how many children are spawned), how frequently IDS is called, how
often the children are killed off, and some other things.  Particularly with the imagemagick stuff,
which uses oodles of memory when processing images, IDS has the potential to go through quite a bit of     
memory.  If nothing else, set your MaxRequestsPerChild value very low (like single digit).
