Does anyone have any ideas for me to check on that maybe causing this ?
rrdtool [info|fetch] work fine on the example .cfg's .rrd file .
routers2.cgi reports itself in good health on the offending *.cfg as well .
From below my best guess is that hte segfault is happening in the line with 'RRDs::updatev' .
And of course I am way over my head with trying to trace that down .
Even even after upgrading to mrtg-2.16.2 , we still get a segfault .

Yes when it segfaults it doesn't do any cleanup .

Not that this is the culprit , but ...
routers2-v2.20-Beta4
Even mrtg-2.16.2 causes a segfault .
