Description
Reported by Andrej Todosic (it@…) in Red Hat's bugzilla: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=201241
Description of problem: When making many graphs, rrdtool eventually stops writing graphs and starts sucking up memory, until all RAM and swap is consumed and the entire machine gets wedged
Version-Release number of selected component (if applicable): rrdtool-1.2.15-3.fc4
How reproducible: Either using the 'larrd' add-on for BigBrother?, or the munin-graph part of munin.
Steps to Reproduce: 1. 'munin-graph --cron' Actual results: Machine runs out of RAM and swap. Kernel fault, requires reboot. Furthermore, the graphs that are drawn are visually very different (anti-aliased?) from previous versions of rrdtool.
Expected results: larrd and munin graph .jpg files created, as they were earlier today.
Additional info: BigBrother? was made from a tarball. It calls rrdtool from bash scripts. munin is munin-1.2.4-9.fc4, which may call librrd.so from Perl modules.
