We have just installed NAV 3.5.4 om a host running 7.1-RELEASE-p5 amd64.
When we try to reach URLs like https://nav.uit.no/rrd/ds=211476/ the page is empty and httpd-error says
child pid 48021 exit signal Segmentation fault (11)
Where do I start debugging? Which process is seg-faulting?

NAV's web interface doesn't spawn any child processes AFAIK, so this must be the httpd child process itself. The page in question will utilize librrd, which could be the culprit. I would try to strace (or is truss the preferred tool on FreeBSD?) the httpd processes.

The cause of the crash was that I had installed both the python-rrdtool library distributed together with rrdtool 1.3.x and the rather antique py-rrdtool package.
