> 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.
