[LB::server addr] returns null
I have put this inside a when LB_SELECTED event.
The wiki says [LB::server addr] will return a null if no member has been selected. Further, it states that one reason for this is that all the pool members are down. Are there any other reasons why no member would have been selected?

Besides the pool member not available another reason why it would fail is if wasn't selected at all. it's assumed that there was another event that proceeded LB_SELECTED that selected the member. - What would happen if the pool has connection limits set and all the pool members were at their connection limit?
- The_BhattmanGood question. I have never tested that scenerio out.

v4 (on the later revs) had a feature where you can override the connection limit on the node when request or connection was received from a persistent user session. This was quite useful in airline booking site, for example. However, the feature was removed or never made it into v9 code and while there is a CR out there, it has not made it back in, AFAIK.
Once the connection limit is reached all pool members, BIG-IP will act as if all the members in pool are down.
