What's interesting about this is that it started not all that long ago
- -- before that, the graphs were instantaneous. I can't really figure
out when it started though. I'm guessing it occurred as a result of a
Solaris upgrade, but it's peculiar to me that this should be a problem
even with a lot of fonts. What system *doesn't* have a lot of fonts?
But thank you for the suggestion to see if they exist/how to see what
fonts are required.
My first thought is that maybe recompiling this would help.

OK, to get the obvious questions out of the way, do all those font
files really exist? Are you running any kind of X11 client that
needs them? If not, can you relocate most of them somewhere else
and see if that improves things?
You should be able to see in the source what fonts are required by
show graph.c

Any ideas? Sorry to repost, but there was nothing but silence
the first time.

Hi all,
I was hoping you might be able to help me with a problem
with showgraph.cgi. It works, but lately it's been taking an
inordinate amount of time to complete. I did a truss on the
process when it runs, and it looks like what it's doing is
opening an endless list of fonts:
stat("/usr/openwin/lib/X11/fonts/TrueType/LucidaSansDemiBold.ttf",
0xFFBF6F28) = 0

fstat(7,
0xFFBF6D60) = 0 mmap(0x00000000,
317896,
PROT_READ,
MAP_PRIVATE, 7, 0) = 0xFE170000 close(7)

...and so on. Any idea why this might have started happening
and what I can do about it? The server OS is Solaris 10
(probably relatively recently upgraded from S10u10 to
S10u11. The graph gets created immediately at the end of
these font openings.

Unfortunately, I'm not especially familiar with Solaris any
more... My suspicion would be that the underlying rrdtool access
is doing this? Is truss equivalent to running strace with "-f" in
follow mode? AFAIK showgraph.cgi itself wouldn't have any reason
to muck directly with the font files...
I suspect it's at least related to rrdtool, but when I do -f (it's
the same as for strace), it is all the showgraph.cgi process ID
doing the work.
