Karpenter is recreating the same type of node over a period of time and deleting it in parallel

[bparamjeet]

Description

Observed Behavior:
Karpenter is recreating the same type of node over a period of time and deleting it in parallel when replicas are increased.

Expected Behavior:
Karpenter should not consolidate often when replicas are increased and new nodes are created , deleted over a period of time marking the pods to be shifted to new nodes.

Reproduction Steps (Please include YAML):

• Create multiple nodepools with same weights and each for an AZ.
• Create a deployment with 1 replica without any nodeselectors.
• Increase the replica count to 10
• Karpenter will create multiple nodeclaims and the pods will be re-shuffled over period of time.

Versions:

• Karpenter Version: 1.0.5
• Kubernetes Version (kubectl version): v1.31
