[rrd-developers] Re: Problem with xport on version 1.2.4

[Tobias Oetiker]

Hi Antoine,
I tried to reproduce this problem but here I get exactly the same
for dump and xport ... so I am a bit lots at the moment ...
you seem to be running with special locales set ... could this be an issue ..

oetiker> ./rrdtool dump test.rrd | ggrep -B2 -A2 920805000
                        <!-- 1999-03-07 12:00:00 MET / 920804400 --> <row><v> NaN </v></row>
