A restarted capi-operator v0.19.0 drops the create events for the provider Deployments it finds already running (kubernetes-sigs/cluster-api-operator#1031). A provider whose Ready condition went False while the operator was down therefore keeps it until that Deployment changes or the informer resyncs, and the first resync after a restart lands two periods later because the handler registers after the informer has listed. With the 10m default that is about 20 minutes, during which capi-providers-core times out on the CoreProvider and everything depending on it waits; every further operator restart starts the clock again. With a one-minute period the same repro recovered 2m02s after the operator took its lease, against no recovery within 4m26s with the default on the same cluster. A resync replays the cache and, with providers in sync, ends in "No changes detected" and an unchanged condition, so it writes nothing to the API server; the operator logged about 15 lines a minute and used 2m CPU and 26Mi of memory. The upstream chart has no value for the flag, so a package patch that make update reapplies adds one, and a bats test holds the rendered argument.
