>
> I've stumbled across the following behavior on a large cluster with large
> number of caches:
> When several new nodes are being added to the cluster, a client node may hang
> infinitely on join. On server nodes one can observe tcp discovery message
> worker continuously processing metrics update messages and writing metrics to
> socket. From the logs it was clear that the cluster generated a lot of
> metrics update messages and a node could not cope with it.
> Even when metrics update message is generated on coordinator, this scenario
> is possible when message round-trip/processing time is compared to the
> metrics update frequency.
> To mitigate the issue, we should drop a not-yet-processed metrics update
> message when a new metrics update message is received.
