The show graph.cgi binary is compiled with the rrdtool libraries, which in turn require some basic fonts to be able to write on the graphs..
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

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.

Well, the fonts exist anyhow. And they existed before the upgrade too.
Luckily, I've been able to determine that the upgrade from Solaris 10u10 to Solaris 10u11 was the start of this problem (had an old BE around and I booted back and everything is fine). That doesn't explain it though.
I recompiled showgraph.cgi too. No real difference. Maybe a little faster, but still runs for 25 seconds just to make one graph.

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.

If you trace it again, can you see if the fonts are being tried in the same order? It might be looking for a specific font family that is now occurring later in the list.
Grasping at straws now... :-)

Well, the fonts exist anyhow. And they existed before the upgrade too.
Luckily, I've been able to determine that the upgrade from Solaris 10u10 to Solaris 10u11 was the start of this problem (had an old BE around and I booted back and everything is fine). That doesn't explain it though.
I recompiled showgraph.cgi too. No real difference. Maybe a little faster, but still runs for 25 seconds just to make one graph.

The show graph.cgi binary is compiled with the rrdtool libraries, which in turn require some basic fonts to be able to write on the graphs..
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:
