• mite treatment should happen in early August
• apiguard: https://www.bienenzuchtbedarf-seip.de/Varroabehandlung-Verdunster-Zubehoer/zugelassene-Behandlungsmittel-gegen-die-Varroa/Apiguard.html
• close mesh bottom because otherwise the Thymol will leave the hive
• wait till the brood is hatched before checking mite load after treatment ~ 18days
• maybe limit entrance during application
• 2 treatments

The initial observed cluster behavior:
1) Constant churn of nodes between Failed and Alive
2) Message bus saturated (~150 updates/sec)
3) Subset of cluster affected
4) Some nodes that are flapping don't exist! (Node dead, or agent down)

One immediate question is how the cluster remained in an unstable
state. We expect that the cluster should converge and return to
a quiet state after some time. However, there was a bug in the
low level SWIM implementation (memberlist library).
