Last modified: 2017-08-16 15:51 EDT
Description of problem:
Cluster is HA: 3 master/etcd, 2 infra, 305 compute nodes
Workload is create 1K projects with 6K pods (4K running) + secrets, services, builds, image streams, etc. Full project spec is here: https://github.com/mffiedler/svt/blob/master/openshift_scalability/config/pyconfigMasterVirtScalePause.yaml
During project creation/scale up the following message

popped 14,720 times - more or less evenly spread across the masters.
Version-Release number of selected component (if applicable): 3.6.105
I'll add full master log location information in a comment.
The logging is unnecessary and does not represent an error condition. The linked GH issue stops logging this normal condition.
PR has merged.
Verified on 3.6.132
