Unless I'm mistaken, the actual reason for your trouble is after adding more nodes, munin-graph needs too much time to run, more than about 300 seconds, resulting in the trouble you see above. Workarounds (quoting munin#1289): | * Apply the patch from #1394 that will quarter the run-time of | munin-graph most of the time. | * Switch to CGI based graphing. Regards, Christoph
