It sounds like PA is neglecting to send a NOTIFY when the first re-registers but is probably sending the NOTIFY when the second re-subscribes. There are quite a few places in the usrloc code where it invokes the PA callback to indicate a change in state. My guess is that one of them is missing or incorrect. Are you using recent code from CVS?
