Just to clarify for all who are reading this thread
1) It's true that the 2.2 connector doesn't support the new Relationship Map structure which is part of APM 10.1
2) From the diagnosis I've done with your team, Biing, and Scott Hahn, your issue does not seem to be related to this issue. On the surface it appears that it may be a defect in the 2.2 connector, but I need to research it further
3) I have data and logs from your environment and am researching the root cause of this issue - I will advise as soon as possible
Regarding the APM Connector 3.0, this is currently in beta. My comment to Scott about this was that if this turns out to be a defect, it will likely be the best course of action to correct it in this new version, since it will also support the 10.1 Relationship Map.
Hope this clarifies the situation,
Jeff
