Some RRD issue with the latest snapshot
The memory RRD fails to render and the logs contain the following message :
php: /status_rrd_graph_img.php: Sorry we do not have data to graph for system-memory.rrd
followed by :
php: /status_rrd_graph_img.php: Failed to create graph with error code 0, the error is: Array
I double checked in the system.log itself and indeed the error message is cutoff like that (nothing after the Array word).
