Hello, we develop an application that maintains users in many jazz instances. With plain java jazz API 4.0 we face the problem, that the API does not allow for more than 5 connections with jazz instances. When we try to connect to the 6th instance, we get these messages:

WARNING: HttpConnectionManager is null.  Connection cannot be released.

Does anybody know if there is a kind of maximum number of connections? And how to overcome that limititation?
