Subscription Client connection limit

Does EventStorePersistentSubscriptionsClient have a limit on the number of connections it can make?
I built a test app, and I could connect to 100, but when i tried to connect to 101, the call to SubscribeToStreamAsync simply blocks.
If I delete one persistent subscription, 101 becomes connected.

Not seeing any errors at Eventstore indicating it was blocked / rejected, and also trid using 2 EventStorePersistentSubscriptionsClient, which then allowed me to create 200 connections.

Switched from 22.0 to 23.0 and no limit
