Comment 1 for bug 2006965

Members going offline should not cause a transition to PENDING_UPDATE. That is not normal.
Member status should only affect the operating status field and never the provisioning status.

Also note, you should never edit that statuses in the database. PENDING_* means one of your controller processes has ownership of the load balancer object and is actively working on it. Some actions have very long retry timeouts (retrying nova failures for example). After those timeouts expire, the object should go back to ACTIVE or ERROR depending on if we could resolve the failure.

Can you provide the configuration settings of this load balancer?
Listeners, protocols, health monitor settings, etc?

Also, can you provide the worker and health manager logs?
