Can henryi have more memory?
I don't know if this is possible, but the consensus health generation script runs out of memory regularly. I never set up alerting to be able to say exactly how often it occurs, but folks have noticed and told me it's stuck, and then magically gets fixed, so I would ballpark it at 2-3 times every 2-3 days.
How much more memory? Don't know. But we could try a gig more and see if that does it?
