Thanks for the followup - so, it appears the issue was down to the RRD perl module segfauling (it has a compiled component). This is probably an RRD perl module install problem - possibly you have multiple versions of the RRDs.pm and RRDs.so in your system and it was picking up incompatible ones?

You might like to consider uninstalling all the RRDTool packages, then checking for RRD executables on the system ( find /usr -name 'RRD*' -print ) and removing them, before re-installing RRD on a clean system, probably with 'make site-perl-install' to get it into the system location. I've come across this problem before, but every time it has given a more helpful message (like 'incompatible module version') rather than just crashing. It may be that mod_perl causes this less helpful behaviour.
