> When new node joins with ZK discovery it sometimes reports negative number of CPUs and incorrect heap size.
> Message in log looks like this:
> {noformat}
> [myid:] - INFO [disco-event-worker-#61:Log4JLogger@495] - Topology snapshot [ver=100, servers=100, clients=0, CPUs=-6, heap=0.5GB]
> {noformat}
> There is a race though between this report and ClusterMetricsUpdateMessage: if the node receives and process this message first which happens in a separate thread correct values are printed to log.
