WS Relay Unsubscribing all subscriptions periodically

[rodgerjohnson]

Description

Our WS Relay periodically closes WS connections without the client initiating the behavior. We only began seeing this behavior after this issue was resolved and we began utilizing the WS_SAME_SUB_FOR_SAME_EVENT="false" parameter.

We're unable to locate what might be causing the relay to initiate this behavior but it looks like unsubscribe is being called to globally shutdown WS connections.

Steps to reproduce

Unable to determine the cause or method of reproducing this behavior. But you should be able to observe this behavior with WS_SAME_SUB_FOR_SAME_EVENT="false" configured, having numerous (5+) newHeads subscriptions and letting it run for an hour or so.
