Hi Jason,
I'm certainly no expert on this, but in the Bugzilla discussion in the Fedora mailing list: https://bugzilla.redhat.com/show_bug.cgi?id=638477#c29 That Henrik quoted below, there is a work-around posted originally by Linus Torvalds (and reposted a bit more friendly here): https://bugzilla.redhat.com/show_bug.cgi?id=638477#c55 This may also work for rrd. Try replacing /usr/bin/firefox in that post with the command to execute hobbitd_rrd, or perhaps more precisely, try prepending: LD_PRELOAD=$HOME/Downloads/linusmemcpy.so to that command. Off the top of my head, I'm not sure where you change that command though in the hobbit config or code. I presume that it can be done though?
Kind regards,
SebA

*face palm*
OK, Let's see if I can figure out how to downgrade glibc.
Note: not a linux user :)
Thanks for this information guys.

Anyone know how I can resolve this issue? The tail end of rrd-status.log lo= oks like this:
2010-11-11 14:43:34 RRD error updating /home/hobbit/data/rrd/xxx.yyy.com/di= sk,H.rrd from 192.168.0.0: This RRD was created on another architecture
The funny thing is, the architecture never changed. I just upgraded Fedora = Core from version 13 to 14.
Could it be an upgrade from a 32-bit to 64-bit version of the RRD library?
I think the problem has been found, but it might be difficult to fix. Look at the Bugzilla discussion in the Fedora mailing list: https://bugzilla.redhat.com/show_bug.cgi?id=638477#c29
Apparently the glibc folks implemented a new version of the glibc routine that does memory-copies fin Fedora 14. And unlike the old version, this one corrupts data when copying between memory areas that overlap.
Interesting bug thread. So the new glibc broke Flash (and rrd), and who knows what else. And even Linus Torvalds thinks it's wrong and unnecessary. And the glibc team seem to be adamant about not changing it.
BSD, anyone?
