@ripienaar FYI: reference to ADR-9 points to page not found. I don't think there is such ADR at the moment?

there seem to be adr-9 in the nats-server repo, so is it just that they have not been moved around yet?

Yeah there's some confusion, @aricart left a gap for me while my KV one is being reviewed and I confused things moving them here. let me fix that

@ripienaar the javascript client in its current incarnation doesn't 'handle' the error, but enables clients to handle it - if the current box is simply whether you can solicit the heart beating then this is handled, however as an automated solution is likely more desirable.
