Channel subscriber limit

[Kera]

How many subscriber can have on channel ? , I saw  max_subscriber_count
 setting in config for group topic ,  If I add 200k user in one channel, do we need to increase the cluster node, currently I am running with 12 cluster node but when I send message into channel , sometime got this error " route join request from proxy to master failed - cluster: load exceeded", I am running tinode on kubernetes with stateful set with this spec

          resources:

            requests:

              cpu: "200m"

              memory: "300Mi"

            limits:

              cpu: "2"

              memory: "2Gi"

max_subscriber_count is the max number of subscribers to a group topic who may be configured to have specific access permissions. This setting has nothing to do with channel readers. Channels don't have a configurable limit on readers. The number of readers is limited by your hardware.
