[rrd-developers] rrdtool dump's core

[Jesper Skriver]

Hi,

I have a problem where rrdtool 1.0.33 dumps core on a FreeBSD
4.3-RELEASE-pl20 box

It can be reproduced as follows:

mie at remie% rrdtool update /data/rrd//renxt1/renxt1.ip.tele.dk.atm1-0.11123-aal5.rrd 1006280441:462185307:2878952554:3880923:4573625:0:u

mie at remie% mv rrdtool.core debug/
mie at remie% cp /usr/local/bin/rrdtool debug/

I have this for lots of my RRD archives, and at first I thought that the
rrd file had become corrupt somehow, but if I delete it and recreate the
rrd file, it's the same thing.

Any ideas ?
