[rrd-users] Strange values in rrd file (rrdinfo)

[Rafal Gwizdala]

Hi, I have created an rrd file and inserted some data into it but today had
some problems with getting the information from it (by rrdinfo). There are
very strange values returned by rrdinfo, by 'strange' I mean very huge, it
looks like there has was some integer overflow. Examples:
rra[0].cur_row = 3266465794
rra[1].cur_row = 1075229722
rra[1].cdp_prep[0].unknown_datapoints = 2560945833
rra[1].cdp_prep[1].unknown_datapoints = 2716709980
rra[2].cdp_prep[0].unknown_datapoints = 2244836241
rra[2].cdp_prep[1].unknown_datapoints = 2806045300

can you please help me explain this?

the RRD can be downloaded from
http://nginn.vipserv.org/temp/4f77541b9f942123c8ff52d6.rrd

and rrdinfo output below.

Best regards
RG
