> Since we are calling {{setDiagnosticsMessage}} in {{nodeHeartbeat}}, which 
> can be called concurrently, the static {{resync}} and {{shutdown}} may have 
> wrong diagnostics messages in some cases.
> On the other side, these static members can hardly save any memory, since the 
> normal heartbeat responses are created for each heartbeat.
