[Bug 1322264] Re: Munin fails to generate graph, stat should be less than end
@nacc: Well one of our customers had the issue that munin-graph was
producing serveral gigabytes (~3GB) of error logs within a very short
time-frame (hours).
the server & client was the latest 14.04 available munin/munin-node
package and the server was unable to poll the munin-node for several
weeks, i guess that triggered the messages.
I'm attaching a munin-graph.log snippet & the corresponding rrd file.

Title:
Munin fails to generate graph, stat should be less than end
Status in munin package in Ubuntu:
Fix Released
Status in munin source package in Trusty:
In Progress
Bug description:
[Impact]
* If rrd data is older than the graph period i.e. a week the graph
fails to generate with error 'start should be less than end'.
[Test Case]
[Regression Potential]
* This is a rather small and obvious bugfix from upstream. The only
issue potentially is if a user manually backported the fix to their
local code. Presuming they took the code directly from upstream, then
there is no problem, as the new code will be identical to their manual
change.
---
If rrd data is older than the graph period i.e. a week the graph fails
to generate with error 'start should be less than end' issue has been
reported and resolved upstream.
Upstream issue http://munin-monitoring.org/ticket/1358 and upstream
fix http://munin-
monitoring.org/changeset/57243edbb3ce8a40a774826b37a1852530778721/munin
The fix is minor, and effects trusty (I've not tested other versions).
