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
open("/usr/openwin/lib/X11/fonts/TrueType/LucidaSansDemiBold.ttf",
O_RDONLY) = 7 fcntl(7, F_SETFD, 0x00000001) = 0 fstat(7,
0xFFBF6D60) = 0 mmap(0x00000000, 317896, PROT_READ, MAP_PRIVATE, 7, 0) = 0xFE170000 close(7) = 0 munmap(0xFE170000, 317896) = 0 stat("/usr/openwin/lib/X11/fonts/TrueType/LucidaSansDemiOblique.ttf",
0xFFBF6F28) = 0
open("/usr/openwin/lib/X11/fonts/TrueType/LucidaSansDemiOblique.ttf",
O_RDONLY) = 7 fcntl(7, F_SETFD, 0x00000001) = 0 fstat(7,
0xFFBF6D60) = 0 mmap(0x00000000, 91352, PROT_READ, MAP_PRIVATE, 7, 0) = 0xFE1A0000 close(7) = 0 munmap(0xFE1A0000, 91352) = 0 stat("/usr/openwin/lib/X11/fonts/TrueType/LucidaSansOblique.ttf",
0xFFBF6F28) = 0
open("/usr/openwin/lib/X11/fonts/TrueType/LucidaSansOblique.ttf",
O_RDONLY) = 7 fcntl(7, F_SETFD, 0x00000001) = 0 fstat(7,
0xFFBF6D60) = 0 mmap(0x00000000, 253724, PROT_READ, MAP_PRIVATE, 7, 0) = 0xFE180000 close(7) = 0 munmap(0xFE180000, 253724) = 0 stat("/usr/openwin/lib/X11/fonts/TrueType/LucidaSansRegular.ttf",
0xFFBF6F28) = 0
open("/usr/openwin/lib/X11/fonts/TrueType/LucidaSansRegular.ttf",
O_RDONLY) = 7 fcntl(7, F_SETFD, 0x00000001) = 0 fstat(7,
0xFFBF6D60) = 0 mmap(0x00000000, 486132, PROT_READ, MAP_PRIVATE, 7, 0) = 0xFE140000 close(7) = 0 munmap(0xFE140000, 486132) = 0
...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.
