I found lots of errors like this in pretty fresh guest cluster in AWS.

This is related to a bug upstream, where services that are not of type loadbalancer still trigger a read action on ELBs. I reported this (or rather added to an issue) but there was no prio on this. With recent changed in our clusters where we allow all ELB actions in our policies (we enabled services of type loadbalancer) we shouldn't see this anymore.

@fgimenez was doing the changes last week

I would check with the updated clusters and then close this.
