>
> Currently, when using the VolatileComponentStatusRepository,we see quite a
> lot of heap used up on the NCM for storing metrics. A heap dump shows that
> the majority of heap utilization is coming from the ComponentStatusReport
> class, each taking roughly 623 KB of heap space (roughly 450 processors, 450
> connections). We store one of these 623 KB objects for each time that a
> "metrics snapshot" is captured - and we do this for each node in the cluster.
> This equates to gigabytes of heap space being used pretty quickly when
> running several nodes each with a couple hundred processors.
