I've heard that with CallManager 3.1+, there can be up to 50 SQL connections per subscriber back to the publisher. Is this correct? Is there any reason to be concerned with more than that? We are using an application to monitor CallManager and by default, it is set to send out a notification when the number of SQL connections to the publisher exceeds 100. We have two subscribers and I see notifications for over 100 connections. I'm just wondering if this is any cause for concern.
I don't think there is a hard or set (enforced) limitation on this. I's assume "up to 50" is all that is supported but if you push beyond that with your application your risking performance and stability issues.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
