+++ This bug was initially created as a clone of Bug #2028963 +++ Description of problem: IP reconciliation is a feature in the latest whereabouts, and due to reports, this feature should be backported all the way to 4.6.z. The feature is in the form of a cron job which reconciles the IP addresses. Version-Release number of selected component (if applicable): 4.6-4.10 How reproducible: Specialized. Customers often experience this when nodes are rebooted, or pods are force deleted, and therefore CNI DEL calls aren't processed in their entirety by Whereabouts Steps to Reproduce: (We will produce a procedure which produces orphaned IP addresses) Actual results: IP addresses will remain stranded, and never utilized again. Expected results: IP addresses that were stranded become available for use again. Additional info: 4.10 has the reconciliation code but still requires a bug fix from upstream.
