> Fighting with cluster nodes losing their lease and shutting down oak-core in
> a cloud environment. For reasons unknown at this point in time, the whole
> process seems to skip about two minutes of real time.
> This is a situation from which oak currently does not recover. Code analysis
> shows that {{ClusterNodeInfo}} is handed the
> {{LeaseCheckDocumentStoreWrapper}} instance to use as store. This is fatal
> since any action the {{renewLease()}} tries to do will first invoke the
> {{performLeaseCheck()}}. The lease check will, when the {{FailureMargin}} is
> reached, _stall the renewLease() thread_ for 5 retry attempts and then
> declare the lease to be lost.
> The {{ClusterNodeInfo}} should instead be using the "real" {{DocumentStore}},
> not the wrapped one, IMO.
