C7 locking up every few days - what do I look for?

I highly recommend installing "Hub Info", it'll let you see memory usage etc. eg:

Driver is a large scale rewrite of the original driver and brings added flexibility in the gathering of ~60 attributes related to general operation of the hub. Driver allows the assignment of these attributes to one of 4 user selectable polling queues and intervals in an effort to allow the impact of the data polling to be minimized (I average around 0.12% of total or less), and the generation of an html attribute for display on a dashboard (template is a text file that may be edited to allow …

Personally, I have found that when ram gets below (and stay's below) 180MB free (out of 512MB total on the C7 and C8), my hub performance starts falling off a cliff. I wrote a rule to reboot my hubs in the early hours of the morning if this happens.
