Yeah, saw it just after I've sent my mail.

Sorry for not reporting it earlier (i.e. before the 4.3.22 final
release). A coworker made me aware of it on Thursday last week, but I
didn't come that far with examining the issue on that day -- and I was
not in the office on Friday. I also first expected a configuration

(changes around GRAPHS_*, etc.)...

Our servers are both x86_64 (called amd64 in Debian) btw.

Well, the main issue is that there was no graph data displayed. If
fixing the RRD update also brings the graphs back, that's fine.
Nevertheless, I'd definitely prefer an empty graph in such a case than
an 1x1-pixel/invisible/no graph.
If there's suddenly no graph anymore, I'd generally expect a bug in
the software. (Yes, I said the opposite above, but that's basically
because there was a lot of configuration to merge -- which tends to be
error-prone. But then again, I that general feeling was right in this
If there's an empty graph, I'd expected issues with reporting in
general and would consider it a local issue which my monitoring

Will apply that patch to the 4.3.22 Debian packages, and roll them out
locally. Will report back as soon as I can confirm or deny that the
