Aaron,
Can you post the commands sent to rrdtool and the result to the rrd-users
mailling list list?
It seems to be a RRDtool problem, and we're abusing RRdtool doing that. :)

Here's some more possibly helpful info:
I changed the rrd_pipe function to allow further debugging:
---snip---
function rrd_pipe ($command) {
if (!is_array($GLOBALS["rrd_pipe"])) {
$GLOBALS["rrd_pipe"]["resource"] =
#proc_open(get_config_option("rrdtool_executable"). " -",
proc_open("/usr/home/aaron/bin/fakerrd",
array(0=> array("pipe","r"),
1=>array("pipe","w")), $GLOBALS["rrd_pipe"]["pipe"]);
$GLOBALS["gc_save_vars"]["rrd_pipe"]=true;
}
---snip---
fakerrd is a shell script as follows:
---snip---
#!/bin/sh
tee /usr/home/aaron/rrdinput.txt | /usr/local/bin/rrdtool - 2>&1 | tee
/usr/home/aaron/rrdout.txt
---snip---
Since I preserve the pipe the php script spits out the same info I
pasted earlier (with the same error). I can now, however, replay
exactly what rrdtool is seeing off-line using the rrdinput.txt file.
The rrdinput.txt file is just the graph ...really-long-line...
statemets like above.
If I replay it, I get this (towards the tail end):
---snip---
597x257
OK u:2.61 s:0.20 r:2.82
597x257
OK u:2.65 s:0.22 r:2.87
597x257
OK u:2.71 s:0.22 r:2.93
ERROR: RPN final stack size != 1
OK u:2.71 s:0.23 r:2.94
Bus error (core dumped)
---snip---
core dump, eh? that's interesting - so it seems rrdtool doesn't
handle large ammounts of piped data well? or do you think it would be
something else?
after noticing the core dump, I checked and saw that the script was
also generating a '/usr/local/jffnms/htdocs/rrdtool.core' when run
from the web interface.
Thanks,
~Aaron
