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...


HTH,
