High memory usage on Sample Node Server

[ainglessi]

When running the gateway against SampleServer-node-opcua subscribed to all machines, memory usage goes up at least to 16GB but publishing never works. @Kantiran91 @mdornaus can this be related to the number of machines? I only had 1-2 subscriptions before and memory use was okay.

With v2 only the situation is similar:
