Cause:
A watch cache is initialized from the global revision (etcd) and might stay on it for an undefined period (if no changes were (add, modify) made).
That means that the watch cache across server instances may be out of sync.
Consequence:
Some operators might get stuck in a hotloop.
Fix:
Fix bug in reflector that couldn't recover from "Too large resource version" errors
Result:
Operators should not get stuck in a hotloop.
