At a first glance, it's not a very general bug, because I'm able to do
something like this:
% rrdtool graph --base 1000 -l 0 testgraph.png -w 800 -h 250 -t 'The number of
currently open inodes.' -v 'number of open inodes'
DEF:a=$PWD/one.domain.tld/ds9.one.domain.tld-open_inodes-used-g.rrd:42:AVERAGE
LINE1:a\#000000:asdf
897x329
%
Or:
% for i in */*.rrd; do echo $i:; rrdtool graph --base 1000 -l 0 testgraph.png
-w 800 -h 250 -t 'Test desc.' -v 'test desc' DEF:a=$PWD/$i:42:AVERAGE
LINE1:a\#000000:asdf; done
[lots of repetitive output]
% echo $?
0
In other words, it didn't hang or crash immediately on something that
simple.
I suppose it will be necessary to recreate the entire Munin setup
(in a chroot perhaps) and run Munin itself over the data set, and
see exactly where and under which conditions it breaks.
