> Project: Sling
> Issue Type: Bug
> Components: Discovery
> Affects Versions: Discovery Base 2.0.12, Discovery Oak 1.2.36
> Reporter: Stefan Egli
> Assignee: Stefan Egli
> Priority: Major
> Fix For: Discovery Base 2.0.14, Discovery Oak 1.2.38

> SLING-10489 introduced "partial startup suppression" sometimes also referred
> to as "joinerdelay" (even though the latter is actually a subfeature of the
> former).
> With this suppression enabled (it is disabled by default), upon a topology
> change the leader instance can loose its leader status even though it did not
> actually leave the topology or crash. This is against the discovery API
> contract, which says that the leader stays leader until it crashes.
