It reads like there are just too many objects in the graph. There is a
constant, MAX_NUM_ENTRIES, but there is code that's supposed to trap this
error.
(1) What is the actual rrd request line - you may need to print it from
frame 5:
(gdb) frame 5
(gdb) print requestedURL
(or you may need to do frame 4 or frame 6)
(2) Try this change (and let me know)
In:
static void graphSummary(char *rrdPath, char *rrdName, int graphId, char
*startTime, char* endTime, char *rrdPrefix) {
char path[512], *argv[6*MAX_NUM_ENTRIES], tmpStr[32], fname[384], *label;
char buf[MAX_NUM_ENTRIES][2*MAX_BUF_LEN],
buf1[MAX_NUM_ENTRIES][2*MAX_BUF_LEN];
...
Make it
char path[512], *argv[12+6*MAX_NUM_ENTRIES], tmpStr[32], fname[384],
*label;
