To answer my own questions, actually, it's fairly simple, and is based on
the number of RRD files matching the testname. The test name that's broken
for me is "bindstats". I have a file called "bindstats.rrd", but I also
have a bunch of other files with names of the form "bindstats,<string>.rrd"
(starting with "bindstats" and followed by a comma and some other text). In
all, there are 14 files matching in this day, for one server, and 11 for
another. It seems that svcstatus.cgi has a maximum of 6 lines per graph, so
for 11 files, it thinks there are two graphs to create (6+5), and for 14
files, it thinks there are three graphs (5+5+4).

I think that my mistake was making different files, for different graphs,
but giving them essentially the same names (with different suffixes
separated by comma). If I rename the graphs to be completely different,
then svcstatus.cgi will only see one file, and won't try to create graphs
for non-existent lines.
