Is it possible to increase the log verbosity to 3 or 4? (-v command line flag)

I have temporarily disabled it while we debug other coredns crashing issues but I will get back to you on that.

Can't think of how can cores be doubled while nodes remain the same, unless node's ResourceCPU was manipulated in some sort:

@eherot Is it possible for you to trace/log the # of nodes and cores with timeline to see if it matches what the controller sees? I'm not quite convinced this is specific to the controller yet. Did it happen on lower CPA version (e.g. 1.6.0) as well?

I wonder would it be related to the k8s client versions --- CPA 1.7.1 uses k8s 1.15.1 where as your cluster uses 1.11.8.

Is there a CPA/k8s compatibility matrix available somewhere?
from cluster-proportional-autoscaler.
MrHohn
commented on August 27, 2024
As client-go is the only piece that may be incompatible, I would refer to https://github.com/kubernetes/client-go#compatibility-matrix. The latest CPA uses client-go 12.0, technically it should work with k8s 1.9+.
