Description (partial)

Symptom:
On a router that is setup as a SSLVPN gateway with multiple policies associated to different VRFs, the tunnel can be seen to establish but no encrypted traffic is seen coming back from the gateway to the client.  

This can appear as intermittent or affecting different users.

Conditions:
Overlapping IP pools are used for the different policy groups (which are set in distinct VRFs), the problem is seen when two users in different policy groups/VRFs are receiving the same tunnel IP address.
