<!-- Please use this template while reporting a bug and provide as much info as possible. Not doing so may result in your bug not being addressed in a timely manner. Thanks! If the matter is security related, please disclose it privately via --What happened: The issue has been observed on Azure but should also apply to other providers as well. On Azure we observed that there are orphaned Public IPs that don't belong to any Kubernetes LoadBalancer service but from looking at the tags and the name it is clear that Kubernetes created them. In the Azure Activity Log, you can see that the Public IP was deleted when the K8s service was deleted but recreated a few minutes later. That re-creation is also visible in the K8s controller manager logs as a reconcile of the service. In our case, we add additional worker nodes and delete services at the same time. I think this leads to the re-creation here Because the service list is retrieved at the beginning of the reconcile loop, services that are deleted while the loop is reconciling a recreated by that loop and afterwards orphaned. What you expected to happen: No orphaned public IPs How to reproduce it (as minimally and precisely as possible): Create a few Kubernetes Load Balancer services (we have around 20). Then scale your worker nodes and delete one service at the same time. Anything else we need to know?: Environment: Kubernetes version (use ): 1.15.0 Cloud provider or hardware configuration: Azure OS (e.g: ): Core OS Kernel (e.g. ): Install tools: Network plugin and version (if this is a network-related bug): Others:

Thanks for reporting the issue. I think this should be fixed during v1.16 release cycle. /milestone v1.16
In the nodeSyncLoop -updateLoadBalancerHosts -lockedUpdateLoadBalancerHosts call chain, I don't see where the mutex lock is obtained.
Hello! I'm the bug triage lead for the 1.16 release cycle and considering this issue is tagged for 1.16, I'd like to check its status. The code freeze is starting on August 29th EOD PST (about 4 days from now) and once the code freeze starts, only release-blocking changes will be considered to be merged.

Is this issue still planned to be fixed for the 1.16 release?
The issue would probably not able to be fixed in v1.16. AFAIK, no one is working on it now.
Thank you for the update! I'll go ahead and remove the issue from the milestone. If anything changes in the meanwhile, please let us know. /milestone clear
