How can such overusage happen?

Can confirm here too. Seen on a node still on v1.53.1 (hasn’t auto updated yet) and another that is on v1.54.2. The v1.54.2 has dropped back to no overuse but the v1.53.1 still has some overuse. It isn’t enough for me to be worried about, but I am curious how this can happen as I haven’t made any changes to the node size.
