> Some methods refresh stub on null, some assume (incorrectly) server is shutting down.
> Most methods reset stub to null on error, and also now we do it when ZK changes.
> One of the latter can cause server reports to not be sent until one of the former methods (e.g. reporting procedure completion) executes and happens to restore the stub for them.
> Also, reset on error is done sometimes with and sometimes without a check.
