Following up *again* with some more debug info. I'm totally new to gdb so this was an interesting exercise :) I grabbed the latest source, and compiled rrdtool. Ran rrdtool under gdb and traced the segfault to rrd_fetch.c apparently around line 310. I uncommented the #define DEBUG at the top of rrd_fetch.c, compiled and ran again. I get this; start 1092006000 end 1099269000 step 9000 rows 808 rra_start 3216956296, rra_end 1099260000, start_off -236105, end_off -1 First Seek: rra_base 416604 rra_pointer 241920 pre fetch -236105 -- nan pre fetch -236104 -- nan pre fetch -236103 -- nan pre fetch -236102 -- nan pre fetch -236101 -- nan [snip -- lots of the 'same'] pre fetch -220299 -- nan pre fetch -220298 -- nan pre fetch -220297 -- nan pre fetch -220296 -- nan pre fetch -220295 -- [and there it segfaults] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFBhaSsmVx2hyhuTucRAhEmAJ0Ujqg8xlBiHbcp/q1i9buxDenZvQCgqdo3 o1FuL1NQNp9ovTH4XmbqJw4= =ghFl -----END PGP SIGNATURE----- -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
