Hi,

there's been one report of this before, on SuSe Linux 8.2, and we
couldn't really figure out what's causing it.

Could you do the following tests, please?

- create a new rrd file

% rrdtool create foo.rrd DS:test:GAUGE:300:0:NaN DS:test2:GAUGE:300:0:500 RRA:AVERAGE:.5:2400:2

- run the following Perl script

--clip--
#!/usr/bin/perl -w

use strict;
use RRDs;

print "Perl version: $]\n";
print "RRDs version: $RRDs::VERSION\n";

my $info = RRDs::info('foo.rrd');
print "file RRD version: " . $info->{rrd_version} . "\n";
print "test exists: " . (exists $info->{'ds[test].max'} ? 'yes' : 'no') . "\n";
print "test defined: " . (defined $info->{'ds[test].max'} ? 'yes' : 'no') . "\n";
print "test2 exists: " . (exists $info->{'ds[test2].max'} ? 'yes' : 'no') . "\n";
print "test2 defined: " . (defined $info->{'ds[test2].max'} ? 'yes' : 'no') . "\n";
--clip--

- mail the results to me

Thanks,
