I suspect that the hobbitd_larrd has a memory problem.

Yesterday I renamed a host, and I noticed that the graphs was not updated anymore on any of my hosts on my primary display server. So I restarted hobbit here.

This morning on my secondary display server, the memory usage was almost total. Attached image shows the graph. It was hobbitd_larrd that was using all the memory. After restart of hobbit on this server the usage came back to normal.
